I do not think that it has anything to do with AGP, as matroxfb does not initiate any AGP transfers. > some info: (cmdline, dmesg, config, lspci -v -v for bridge/card): > > video=matroxfb:vesa:0x1bb 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.
