Kernel panic, obtained from remote console
I've done some research, and apparently this is not a software problem. The strange thing is that didn't happen in win7 :( I am reopening this bug, because although I get MCE exception, the driver hangs in attempt to switch to text console to display the MCE panic. Created attachment 54573 [details] [review] Use mdelay instead of msleep Does this patch fix the hang when switching back to console after the MCE? Thanks, I will test this, but it may take some time for MCE to happen again. I will report with the result here. Yes, this fixes the hang after and MCE, and it shows the error log on the screen. Any, clues how to debug this MCE error? It doesn't happen in windows, so I guess some driver didn't program some piece of hardware right. Thank you. (In reply to comment #13) > Yes, this fixes the hang after and MCE, and it shows the error log on the > screen. Great, thanks for testing. Note that in general a bug report shouldn't be resolved before the fix is applied or at least submitted, but anyway I've submitted it now. > Any, clues how to debug this MCE error? Unfortunately not.

Created attachment 54554 [details] Kernel panic, obtained from remote console Hi, I experience some random kernel hard lockups. It appears that this happens after some time normal working. This time it happened in firefox, but it hanged in Doom3 also. I managed to get some debugging info. If you want some other debug info, just let me know. I am attaching system and debug info. xf86-video-ati 6.14.3-1 ati-dri 7.11.2-1 mesa 7.11.2-1 Linux drago 3.1.5-1-ARCH #1 SMP PREEMPT Sat Dec 10 14:43:09 CET 2011 x86_64 AMD E-350 Processor AuthenticAMD GNU/Linux
