Still trying to track down a small problem with my Matrox G400 video
card (which I asked about last week), which I'm suspecting might be
related to these kernel warnings:
Jul 31 09:14:58 kernel: PCI: Cannot allocate resource region 0 of device 01:00.0
Jul 31 09:14:58 kernel: PCI: Failed to allocate resource 0(d8000000-d8ffffff)
for 01:00.0
(device 1 is the video card), and this warning in XFree86.0.log:
(WW) MGA(0): Video BIOS info block not detected!
lspci reports:
01:00.0 VGA compatible controller: Matrox Graphics, Inc. MGA G400 AGP (rev 04)
(prog-if 00 [VGA])
Subsystem: Matrox Graphics, Inc. Millennium G400 16Mb SGRAM
Flags: bus master, medium devsel, latency 32, IRQ 15

Kernel 2.4.6, with mtrr enabled. X 4.0.3. 16Mb VideoRam.
Cat /proc/mtrr reports:
reg00: base=0x00000000 ( 0MB), size= 128MB: write-back, count=1
reg01: base=0xd6000000 (3424MB), size= 16MB: write-combining, count=2
reg05: base=0xd0000000 (3328MB), size= 64MB: write-combining, count=2
There was some discussion of seemingly related problems in the kernel
mailing list archive some months ago, but nothing that suggested a
course of action. Has anyone any advice? Or where can I learn more
about this stuff?
I'd really appreciate any guidance anyone had to offer,
Jim
