Re: X lockup, 4 head OpenGL
I'm still having trouble with X locking up and "IRQ XXX disabled" messages.
I am on motherboard #3 now -- this one does actually assign two different IRQs to the different cards, but my problem persists.
Linux kernel 2.6.13-4
Two FX 6600-GT graphics cards, not connected with the SLI bridge connector.
4 independent X screens
Basic openGL programs don't seem to cause problems (glxgears, ssystem...) but my program does.
I am using "advanced" features of the drivers, such as fragment shaders, glXGetVideoSyncSGI(), glXAllocateMemoryNV(), etc.
The lockups (not always a total system freeze) are often preceeded by a "Disabling IRQ xyz" error.
It only seems to happen when all of the below conditions are true:
a) Both CPU cores are active
b) I am using two video cards
c) I am using both outputs on at least one card.
Is there any way the "new driver" will address my problem?
My only other option (that I know of) is the quad PCIe motherboard from Gigabyte, but I don't think I can buy that yet (anyone know?)
