Hardware problem? PCI resource conflict, IRQ for instance? Does resetting the adapter in its own BIOS to factory settings help? Is the drive attached when you have a problem? Does the Adaptec work in a different PCI slot? Perhaps in a different machine? Can you lend a different adaptor, such as a Tekram DC-390F or U2W (Symbios 53C8XX based, so different driver needed) and try that? > The last driver loaded is the ppc0, parallel port driver. At that time, there should have been a few log lines for ahc0, please show that - and please show a dmesg of your working system (without the Adaptec installed). Do you see a message similar to this: Nov 30 02:40:10 libertas /kernel: Waiting 5 seconds for SCSI devices to settle On my machine the ahc0 lines (of a 2940 UW Pro) are: Nov 30 02:40:10 libertas /kernel: ahc0: <Adaptec 2940 Pro Ultra SCSI adapter> port 0xe800-0xe8ff mem 0xe3020000-0xe3020fff irq 15 at device 8.0 on pci0 Nov 30 02:40:10 libertas /kernel: aic7880: Ultra Wide Channel A, SCSI Id=7, 16/253 SCBs -- Matthias Andree
