3.5.0-37-generic still affected Occurs most often under combined USB hard disk data transfer + at times heavy CPU and GPU load Must remember to take photo of the panic (though it scrolls off the screen and the useful bit at the top is missing)

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. --- AlsaVersion: Advanced Linux Sound Architecture Driver Version 1.0.25.
