next in thread | raw e-mail | index | archive | help
I just got the Adaptec 4 port IDE raid card 2400A.
It doesn't probe right:
asr0: could not map memory
I added some debug printouts to the asr driver and pci code.
asr0: <Adaptec Caching SCSI RAID> mem 0xf6000000-0xf7ffffff irq 5 at device 5.1 on pci2
pcib2: device asr0 requested unsupported memory range 0xf6000000-0xf6400000
pcib2: device asr0 requested unsupported memory range 0x0-0xec9fffff (decoding 0xec900000-0xec9fffff, 0xf6000000-0xfbffffff)
asr: map failed at: 2602 p:f6000000 f6400000 l:00400000
asr0: could not map memory
device_probe_and_attach: asr0 attach returned 6
wtf is going on here?
