First a disclaimer: I'm running this on Jaunty because that was the easiest way to get hdmi audio out on my intel x4500hd video. - I know it's not an officially supported platform.

Kernel: 2.6.28
XBMC: pre-9.04 r18324 (compiled Mar 7 2009) - installed via the svn ppas
Intel 2.6.1 display driver

The gnome desktop seems to work fine, firefox, etc launch and run indefinitely. glxinfo reports direct rendering: yes and glxgears gives ~1200 fps

I can access my movie collection via XBMC and play .iso .wmv and .avi test files with no problems.

I've been running with XBMC windowed for setup & testing purposes.

On certain plugins, for example Apple Movie Trailers, I'll drill down, the list will populate with trailers and then the system locks up.

I can still move the cursor, but clicks don't work. The screen doesn't update (gnome clock stops, cpu graph on gnome desktop stops, etc.).

Switching to virtual consoles doesn't work.

The system does respond to pings, though and I can ssh in. Commands like ls, du, df, man, lspci, ps, top all seem to work fine - and top reports 0-1% cpu util on both cores.

Here's where it gets weird: "ps a" hangs the ssh session completely. ctrl+c does nothing. I can open as many ssh sessions as I want, but as soon as I issue the ps a command, the session hangs and I end up having to close the terminal.

If I run xbmc via gdb per this post http://forum.xbmc.org/showthread.php?tid=30230 , I can SSH in to the locked machine, ps a works, and I can kill the gdb and xbmc.bin processes and regain control of the desktop. But I never get the chance to get a backtrace from gdb.

Neither the X log, system log nor xbmc logs seem to show anything glaringly wrong - I wonder whether there's even a chance for the process to write to the log before the lockup.

As a test, I also installed boxee. There, if I drill down to Friends activity, and pick a recommended video, the system locks up in an identical way.

Here's the tail of my xbmc log:

Code:

[/xbmc@mediator:~$ tail -n 50 /var/tmp/xbmc-xbmc.log

So my question is, where do I go from here? How can I troubleshoot this issue?

[Maxim]

Wow. I'm going to bump this for the sake of curiosity. You did a great job on the description too. I understand your situation and can't think of anything that you can do. You even went as far as trying to get a backtrace for the devs, kudos to you. The devs are going to have to step up to bat for this one. I can only assume that it's something with CPU scheduling, where something happens and everything in the OS gets stuck cause XBMC is holding authority of the CPU cycles (Just a guess, i'm no programmer.). I've see this type of stuff happen on different OSes with different applications over the years.

The only thing I would ask of you is to post the full debug log, and not just a tail. Pastebin is a common location to post up these types of things.

Also, you're not the only jaunty user due to Intel drivers. I'm using alpha3 and not experiencing anything like this.

[althekiller]

You can kill xbmc with "killall -SEGV xbmc.bin" to generate a core file then examine it for deadlock (obviously the problem here) with gdb. You may need to launch XBMC from the console for the core to be generated properly.

You will also probably have to turn on cores before launching xbmc from that terminal

Code:

ulimit -c unlimited
xbmc

Run it till it locks then do the killall above. You should see "Segmentation fault (core dumped)" in the terminal window and there should be a core.XXXX file in that directory.

[xbmcJJ]

Thanks everybody for your suggestsions. I may tackle this again in the future, but for now, I give up.

I launched XBMC like this:

ulimit -c unlimited
xbmc

Browsed plugins until it locked up, then ssh'd in and tried:

killall -SEGV xbmc.bin

Machine stayed locked. X unusable. and "ps a" from an ssh session hangs indefinitely.

Here's the last log:

http://pastebin.com/m626daa2b

The good news is that I had a spare partition on the disk and installing Intrepid + intel xserver from xorg-edgers ppa + 2.6.28 kernel from jaunty + libpulse-dev + compiling XBMC from the SVN yields a working, stable configuration.

gl performance is crappy, compared to jaunty install, but good enough for xbmc (i won't be playing games on it) and watching movies & internet streams.

[Redth]

I'm having this exact issue now too...

For me, it seems like the xbmc.log always shows the last thing that happened was a call to FileCurl to download some type of file. It happens mostly when scanning content (which makes sense since there's a lot of FileCurl calls in that process), and it does not hang at the same point each time. For example the system will hang while scanning a tv show, when I restart and launch xbmc, and start scanning again, it picks up where it left off, scanning the tv show that made it hang, and carrying on, then hanging a bit later again...

I have an ASUS P5E-VM, and am running Jaunty with all the latest updates. I'm also running Revision 23535 (I configured with --enable-external-libraries).

The next thing I'm going to try tonight is installing some newer Intel drivers from this post: http://ubuntuforums.org/showthread.php?t=1130582

If xbmcJJ was able to get intrepid working with the xorg stuff from xorg-edgers ppa, maybe this will be of some help to me.

Any other ideas? I wouldn't think this is a graphics issue, but who knows. I've used xbmc to play videos back fine for hours without issues, it seems as if it only happens when I'm scanning for content, or I suppose, whenever xbmc is fetching a file from the net via FileCurl.

Help is much appreciated!

Same hardware..
Same Problem..

Solved it by Hardy, now everything runs smooth!

Same hardware..
Same Problem..

Solved it by Hardy, now everything runs smooth!

So you downgraded all the way to Hardy?

That seems to be the trend. If this is a bit more widespread than anyone thought hopefully we can get it working right in Jaunty. obviously something changed since Intrepid to Jaunty that's causing this. Doesn't seem like a great solution to downgrade to older software

[jverdeyen]

I know, but I had everything working, remote, lcd, .. the only thing was the freezing on scan issue... so I got back to Hardy! No problems, no issues (except soms vsync problems while playing videos, which I should invest later on..).

I did .xbmc dir backup, and clean install. Fixed in less than one hour.

[CrashX]

I have the same issue .. Sometimes it hangs on database scan and it basically looks up my machine .. I can't get back to Ubuntu desktop .. Ctrl+Alt+F1 doesn't even work after it hangs ...

I did upgrade from Hardy to Jaunty instead of clean install ? Are you guys doing the same ?

I never had this problem on Hardy ..

[Redth]

I did a clean install of Jaunty, so I don't think that upgrading is the issue...

When I get home I'm going to try it again.. I don't want to lock up my machine from here since I can't physically reboot it, and I need it for ssh

But I did upgrade to the X-Updates PPA for Jaunty. I'm hoping that might help fix things... Doesn't seem like it should be a Graphics driver issue though...

[jverdeyen]

I did a clean install with Hardy.

I migrated from MediaPortal (windows) to XBMC (linux) last week, it runs 100x faster, smoother and it's just better, but that was my only point to get back to MediaPortal.

I didn't want to give up so I tried a clean Hardy install, which resulted in a success.

It seems like some people also having these freezes, just try to get back to Hardy... and wait until this problem is fixed?

[Redth]

It doesn't seem like anyone's working on the problem, so I hesitate to go back to Hardy or Intrepid and avoid the problem.

I was a Mediaportal user too, but mainly for the dvb aspect, which I'm not using anymore... I've always liked XBMC better, and it's leagues ahead these days... Plus, Windows requires a lot more overhead than linux, and is less configurable... I also have an old XBOX running xbmc in my bedroom that streams from my main HTPC (the system having the issues with freezing).

I'm willing to try and help figure this out, but I'm not sure what else to do!

[jverdeyen]

I've looking for all kind of issues:
- network
- samba
- nfs
- display driver
- ..

there are so many types of freezes in ubuntu reported on the internet... dead end

[CrashX]

The only reason I upgraded to Jaunty was due to this issue ? http://forum.xbmc.org/showthread.php?tid=56693 ..

Has this been resolved in Hardy ?

Anyone able to get a crash dump ?
