Comment 23 for bug 1167624

Thanks everyone for their input. It sounds as if it can be reproduced when doing some multimedia activity (heavy video playback and / or audio). That's starting to look like a common denominator as of late.

I know it seems to be random for folks, but, does there appear to be any average amount of time or activity that seems to trigger this more than others (i.e. how long into listening to audio / watching video) does it happen? Does the CPU fan start revving up at all or does the system get warmer than usual when this happens? I'll also try to replicate this using suspend / resume, etc. The XPSes I have don't lock up on me (yet) after quite a bit of use, but, I'm willing to try and mimic some of you guys' behaviors to see if I can get the same things to happen.

@epervieror: If you have more than one system available, setting up a netconsole would be a good tool to try and catch something from the system: https://wiki.ubuntu.com/Kernel/Netconsole
The REISUB recommendation from the forums is also a good idea to try and un-wedge the system when it gets in this state.

I know at least one of you have run through hardware diags with Dell and not found anything, but, I'd also be curious to see what the following tests yield on some of your systems out there (run the CPU burn test at your own risk as I wouldn't want anyone to fry their machines): https://help.ubuntu.com/community/FaultyHardware

Thanks!
