I didn't see this mail in time. I did show a few folks the corruption,
ran the kernel with drm.debug=4, etc. and checked the modelines. xrandr
and the kernel seem to report the same modes each time, but obviously
the display is shifted. I see various changes in git (everything from
EDID reading to actual modeline changes in the i915 code - various weird
margin settings seem to exist that might well cause some offset in the
display) that could be responsible, so I will bisect it now for you.

My concern with the email list is that it's listed in the MAINTAINERS
file, but it's essentially of no value to bug reports unless they are
already subscribed to it (moderation is fine, even auto reject after 3
days - a standard mm feature, but I feel auto-reject is a little too
harsh). Needless to say, I'm subscribed now :)

Thanks,

Jon.
