I got some BUG_ONs/warnings from the kernel, and every time it happened I ended up with a garbled screen (see attached photo). Switching to a virtual console, and back to X (twice) restored my desktop.
I don't know if the kernel is trying to switch to a text console to display the Oops, or if it tries to display the oops on the graphical console, but apparently its not working well.
The first time I get an Oops after a reboot I get to see the Oops text on a black background (and my mouse cursor, which makes me believe this is the graphical KMS console), but everything after that just leaves me with a garbled screen.
The oops displayed is: https://lkml.org/lkml/2011/6/15/50
I don't know if this is a regression or not, I rarely get Oopses, and last time I got a panic message I was able to see it (although I was in X at the time), but then so can I for the 1st Oops message.
My graphics card is: 01:00.0 VGA compatible controller: ATI Technologies Inc RV730 PRO [Radeon HD 4650]
I use KMS, Xorg 1.10.2, and Mesa 7.10.2-3.
