Public bug reported:
Hi,
Running Ubuntu 12.04 LTS (64-bit) on a standard business desktop PC (HP
Compaq 6005 Pro SFF) I used to experience daily hangs with/without
kernel panic. The panics seem GPU-related.
I run two desktop PCs side-by-side of identical hardware.
Installing the Quantal Hardware Enablement stack fixed the stability
issue at last (after suffering it for several months).
In a recent kernel upgrade, sadly a daily kernel panic has returned, it
occurs 1-2 times daily.
This may be kernel 3.5.0-34 or 3.5.0-32, I can't identify which one.
Both were installed in June around the time this started.
>From the stack trace on-screen it doesn't seem to be the same crash and
doesn't mention DRM this time but is the same in nature, i.e. I am doing
something in the GUI and I get a kernel panic. (This has also happened
when I am out of the office.)
Graphics card:
01:05.0 VGA compatible controller: Advanced Micro Devices [AMD] nee ATI RS880
[Radeon HD 4200]
I upgraded my second PC to 12.10 recently then it booted onto a black
screen (power management), I could not get past this, so I upgraded to
13.04 from a single-user mode root maintenance console. My second PC
running 13.04 is now stable on this hardware.
My 12.04 LTS PC with the latest security/critical updates is again not
stable.
