Hi,
I use Fedora 17 and as soon as kernel 3.5 has been distributed, I get very bad rendering artifacts on my laptop.
The laptop is a Thinkpad R50 with a radeon graphics card
01:00.0 VGA compatible controller: ATI Technologies Inc Radeon RV250 [Mobility FireGL 9000] (rev 02)
It is not a new laptop, about 8 years old. I've opened a bug at Fedora where you can see 2 pictures of what happens.
https://bugzilla.redhat.com/show_bug.cgi?id=845639
Reading the mailing list, I cannot understand if this problem has already been reported.
I've tried to bisect but I've hit a series of unbootable kernels.
"git bisect visualize" currently shows the log between
BAD: be122ab Merge tag 'spi-for-linus' of git://git.secretlab.ca/git/linux-2.6 GOOD: c10e408 i915: Add option to bypass vbt table.
where I can see a lot of drm related changes.
Regards
