PATCH: intel drm: fix reproducable kernel panic
Hi,
Short intro: I'm a Linux enthusiast / developer. Lately I'm mainly active
writing kernel drivers and as a developer for Fedora.
I don't know what the proper place is to send bugs for intel drm issues, and
you are a recent committer to the i915 drm driver, so hence this mail.
During the testing of Fedora 9, I've noticed that any OpenGL use hard freezes
my machine with a kernel panic (blinking keyboard leds).
Today I've attached a serial console to capture the panic output. This has lead
to me finding out that the panics are caused by a setting in my drirc, namely:
"Always synchronize with vertical refresh"
Further investigation has let to me localizing and fixing the bug, patch
attached.
Regards,
Hans
