The hardware is this: Mainboard: Tyan Trinity K7 S238 CPU: AMD Athlon K7 750MHz Memory: PC-133 128MB Boot HD: Seagate 9.1GB LVD SCSI HBA: Tekram DC390U2W PCI I continue to get these warnings at boot-time: 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, which is a Matrox G400 AGP. 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 Memory at d8000000 (32-bit, prefetchable) [size=16M] Memory at d4000000 (32-bit, non-prefetchable) [size=16K] Memory at d5000000 (32-bit, non-prefetchable) [size=8M] Expansion ROM at [disabled] [size=64K] Capabilities: [dc] Power Management version 2 Capabilities: [f0] AGP version 2.0 The card basically works, but I get problems under applications that make heavy demands (programs hang or produce seg-faults). I've had the warnings ever since upgrading from the 2.2.x series to the 2.4.x series. I gather from the archives that this is a known problem, and that it has been discussed quite a bit. Is there a way I can help track down the problem, or a proposed solution that I could try? Thanks a lot, Jim McCloskey
