VGASwitcheroo enabled hybrid setup with Intel Arrandale and Radeon CEDAR
01:00.0 0300: 1002:68e0 (rev ff) (prog-if ff)
!!! Unknown header type 7f
Kernel driver in use: radeon
(lspci -vn). When the Radeon is powered down and X is running dmesg is filled up with thousands of
radeon 0000:01:00.0: IH ring buffer overflow (0xFFFFFFFF, 15, 65550)
which does not disappear, even if debug is disabled. I think the radeon driver does not understand that it's card is powered down. Can this be fixed?
There seems to be something up with "the ring", I've got a problem since post 2.6.35: https://bugzilla.redhat.com/show_bug.cgi?id=691326
I think this should be fixed in a newer kernel. Can you try with a newer kernel?
