Dear everybody (sorry troy, if you get this twice), This is another error report on the aic7895 on the intel dx440lx. I have now tried with Alan Cox's 35pre1 patch applied to the clean 2.0.34 source tree. I get slightly changed error messages. The core of the problem seems to be that my scsi-controller gets assigned irq 0 and memory 0x0. To recapitulate: I have a PII333 dual on a intel dx440lx motherboard. I have redhat 4.2 installed on ide-disks. So that part is OK. I have (for the test case only) atached a single scsi toshiba cd-rom xm 6201b on channel a, which is terminated by jumper setting. It is reported to have id 1. The cabling looks like daughter card --------- motherboard ----------- cd-rom I have enabled termination of the motherboard part. the scsi bios is reportedly: adaptec aic7895 scsi bios 1.32S2 - idk4 New kernel messages I have written down (by hand): +++++++++++++++++++++++ (scsi0) <Adaptec aic7895 ultra scsi host adapter>: found on pci 9/0 (scsi0) Wide Channel A, SCSI ID=7, unknown interrupt 32/255 SCBs (scsi0) BIOS enabled, IO port 0x0 IRQ 0 (scsi0) IO memory at 0x0 MMAP Memory at 0x0 (scsi0) Couldn't register IRQ 0,Ignoring (scsi0) <Adaptec aic7895 ultra scsi host adapter: foun on pci 9/1 (scsi0) Wide Channel B, SCSI ID=7 32/255 SCB's (scsi0) BIOS enabled, io port 0x0 IRQ 0 (scsi0) IO memory at 0x0 MMAP Memory at 0x0 (scsi0) couldn't register IRQ 0,Ignoring scsi: 0 hosts scsi: detected total <snip> Partition check hda: +++++++++++++ Then it were hanging. Clearly I want it to use IRQ 11 and memory F400h and F800h, not the ones reported. How do I do that? Have a nice day.
