Could you report the entire line, please ? Given the message above, the driver is seeing a bogus PCI BARs=20 configuration: - The MMIO region is reported as a 0x2000=3D8Kb window that should in=20 fact be 256 bytes. - The on-chip RAM region that should be 8Kb large is not reported. This let me think that the region reported as MMIO might well be=20 the on-chip RAM region, btw. > irq 9 at device 11.0 on pci2 > sym0: failed to allocate RAM resources The driver probably allocated the 8K region as MMIO and failed when trying to allocated the on-chip RAM resource (next PCI BAR). > Faltal trap 12: page fault while in kernel mode >=20 > This with a SCSI Host adapter SYMBIOS 53c895a. >=20 > Can You please help me ? It would be interesting to have the actual values of the first 64 bytes of the PCI configuration space for this 53c895 chip. Regards, G=E9rard.
