2.6.0-test1 + matroxfb = unuusable VC

i'm seeing the exact same issues. i use to see similar problems in late 2.4's with agp turned on, where turning off agp sorted out the issue. using 2.6 (test1-ac2), it happens whether agp is turned on or not.
I do not think that it has anything to do with AGP, as matroxfb does not initiate any AGP transfers.

I think that you are using fbset somewhere in your initscripts. Either do not do that, or apply ftp://platan.vc.cvut.cz/pub/linux/matrox-latest/matroxfb-2.5.72.gz.

PCI: No IRQ known for interrupt pin A of device 01:00.0. Please try
using pci=biosirq.
And reconfigure your system to assign IRQ to the AGP devices too. matroxfb uses it for delivering some notifications to the userspace programs...

Interrupt: pin A routed to IRQ 0
... if it hooked IRQ0 as MGA interrupt, anything can happen.

indeed, the issue would only happen after switching from x back to console. regardless, not building agp worked aorund the 2.4 problem for me.

i am pretty sure no fbset is being employed; i find no reference to it in /etc, nor does it seem to be installed anywhere. i certainly haven't set it up myself on this machine.

is this a bios issue? if not, need i try anything save the suggested irq=pcibios? i'll report once i get home and can try things out; thanks!
