[Ubuntu-x-swat] [Bug 774978] Re: xserver crashes in RecordAReply when XRecord is enabled in syndaemon
Thanks Bryce for this wonderful explanation. I was wondering what the real problem is.

[Ubuntu-x-swat] [Bug 771169] Re: X crashed while browsing with Chromium (librecord.so related?)
How can we get the full stacktrace for a bug like this? For me, it happens once every couple days (sometimes once a day, sometimes once a week). But I can't reproduce it on demand (i.e. while running X under gdb). The only solution that I know if is to use a library like this (I wrote it): https://github.com/certik/stacktrace compile it with Xorg, and then wait. I didn't have time to do it yet, so I don't know if it is actually going to work. Any help is appreciated. -- You received this bug notification because you are a member of Ubuntu-X, which is subscribed to xorg-server in Ubuntu. https://bugs.launchpad.net/bugs/771169 Title: X crashed while browsing with Chromium (librecord.so related?) ___ Mailing list: https://launchpad.net/~ubuntu-x-swat Post to : ubuntu-x-swat@lists.launchpad.net Unsubscribe : https://launchpad.net/~ubuntu-x-swat More help : https://help.launchpad.net/ListHelp

*** This bug is a duplicate of bug 771169 *** https://bugs.launchpad.net/bugs/771169 Marcelo marked it as duplicate for #771169, and it seems it is. Thanks! Indeed, in all my stacktraces above, the list shared lib is /usr/lib/xorg/modules/extensions/librecord.so so the problem is probably there. -- You received this bug notification because you are a member of Ubuntu-X, which is subscribed to xorg-server in Ubuntu. https://bugs.launchpad.net/bugs/778261 Title: Periodic Xorg crashes in intel_drv.so ___ Mailing list: https://launchpad.net/~ubuntu-x-swat Post to : ubuntu-x-swat@lists.launchpad.net Unsubscribe : https://launchpad.net/~ubuntu-x-swat More help : https://help.launchpad.net/ListHelp

I spent some time yesterday and polished the stacktrace code and uploaded here: https://github.com/certik/stacktrace now we just need to hook this in, test it, and then wait.

[Ubuntu-x-swat] [Bug 778261] Re: Periodic Xorg crashes in intel_drv.so
Hi Juan, you are right, I just changed the summary. This bug is supper annoying, as I always loose all my work. How should we debug it? The best would be to figure out some way to reproduce it reliably, but that seems like a very hard problem. So a better way would be to somehow use the memory addresses in the stacktrace to figure out where in the code the problem happens, and then add some debug prints over there. Here is the stacktrace, anyone know how to proceed? [ 4343.791] 0: /usr/bin/X (xorg_backtrace+0x26) [0x4a2626] [ 4343.791] 1: /usr/bin/X (0x40+0x6219a) [0x46219a] [ 4343.791] 2: /lib/x86_64-linux-gnu/libpthread.so.0 (0x7f491f9a+0xfc60) [0x7f491f9afc60] [ 4343.791] 3: /usr/lib/xorg/modules/extensions/librecord.so (0x7f491d355000+0x2920) [0x7f491d357920] [ 4343.791] 4: /usr/bin/X (_CallCallbacks+0x34) [0x432af4] [ 4343.791] 5: /usr/bin/X (WriteToClient+0x21a) [0x461c9a] [ 4343.791] 6: /usr/lib/xorg/modules/extensions/libdri2.so (ProcDRI2WaitMSCReply+0x52) [0x7f491cd3cd82] [ 4343.791] 7: /usr/lib/xorg/modules/extensions/libdri2.so (DRI2WaitMSCComplete+0x59) [0x7f491cd3b479] [ 4343.791] 8: /usr/lib/xorg/modules/drivers/intel_drv.so (0x7f491cae8000+0x25030) [0x7f491cb0d030] [ 4343.791] 9: /lib/x86_64-linux-gnu/libdrm.so.2 (drmHandleEvent+0x108) [0x7f491cf46478] I have one idea. The stacktrace above seems to be generated by this code here: https://github.com/jolicloud/xorg- server/blob/2a006327f17f448461aecc715fabef1b0d9caa1f/os/backtrace.c however, there is a way to obtain way better stacktrace (with files and line numbers!) using code, that I wrote. So one way to go forward would be to replace xorg_backtrace() with my own code. Then, I will introduce some simple bug in the code, like "char *p=NULL; *p=1", to test it. If it works, then I'll simply wait couple days, and once it crashes again, we'll nail it down. -- You received this bug notification because you are a member of Ubuntu-X, which is subscribed to xorg-server in Ubuntu. https://bugs.launchpad.net/bugs/778261 Title: Periodic Xorg crashes in intel_drv.so ___ Mailing list: https://launchpad.net/~ubuntu-x-swat Post to : ubuntu-x-swat@lists.launchpad.net Unsubscribe : https://launchpad.net/~ubuntu-x-swat More help : https://help.launchpad.net/ListHelp

And it crashed again today. I will keep reporting every single crash. There should be a pattern emerging, that hopefully will allow me to debug what is going on.
