Bug#262751: kernel-image-2.6.7-powerpc: radeonfb fails to wake chip from D2
Package: kernel-image-2.6.7-powerpc
Version: 2.6.7-4
Severity: normal
Hi,
The radeonfb driver on my iBook does not bring the display back properly
after sleeping. After sleep the backlight turns back on but the display
remains completely dark. I have had this problem with the old and the
new radeonfb driver and various 2.4 and 2.6 kernel versions. This
problem started after I sent the iBook back to Apple about 10 months
ago. I think the motherboard was replaced at that time. If I disable
suspend to state D2 [1] then resume works as expected. Other notes of
interest:
- I tried to find the culprit in
drivers/video/aty/radeon_pm.c:radeon_set_suspend() by selectively
removing parts of that function. I did not find a combination that
improves the situation.
- I tried twiddling with the backlight keys after sleep. I can turn
the backlight off, and back on, but the display remains black.
- I tried switching between console and X, to different consoles, and back,
etc. The switching works, apparently, but still a black display.
- OSX successfully brings the display back after sleep. I don't know
how to tell if OSX is putting the chip in state D2.
Any clues for other things to try?
Thanks,
David
[1] : This patch allows my laptop to sleep and resume as expected.
