next in thread | raw e-mail | index | archive | help
I have just installed an NCR-815 PCI SCSI controller in my PC.
When I boot 2.1.0-951026-SNAP (off IDE) I get the following error:
pci_map_mem failed: device's memrange 0xc8000-0xc80ff is
incompatible with its bridge's memrange 0x4000000-0xffffffff
After this the driver still detects sd0 correctly, but I'm unable
to access it in any way.
Occasionally (with cache enabled) the above error is followed by:
CACHE TEST FAILED: reg dstat-sstat2 readback ffffffff.
CACHE INCORRECTLY CONFIGURED.
Disabling the cache doesn't prevent the pci_map_mem error.
What does all this mean? Do I need a new motherboard?
Have I got a duff NCR815? Thanks in advance for any help.
Full dmesg output follows below.
