Description Cedric Sodhi 2011-05-02 13:40:44 UTC
I can't tell much more than that.

WITH or WITHOUT "Cedar" firmware compiled into the kernel, the combination VGASWITCHEROO && Radeon (+KMS) {M} && i915 (+KMS) {M} && AGP {M} && <other relevant items as {M}> causes problems, log attached, I think it speaks for itsself.

Readeon and Intel being {M} is enough for this to happen.

Is this still an issue with kernel 3.1?
Comment 4 Alex Deucher 2014-01-09 20:48:20 UTC
Is this still an issue with a newer kernel?

Can't tell, as I don't possess the h/w any more. Feel free to close.
