Hi,
I have an old HP 625 laptop with an ATI RS880 HDMI Audio [Radeon HD
4200 Series]
chip on board.
The xf86-video-ati driver needs DRM (direct rendering support) in the
kernel.
Unfortunately, if (and only if) I enable DRM (built in or as module) in
a recent kernel
like gentoo-sources-3.10.9, the kernel freezes with a blank screen
during boot, i.e.
long before xorg-server is started (only by hand in my case).
So, what can I try to fix this (some IOAPIC switches on the boot
command line)?
Many thanks for a hint,
Helmut
