I have a similar problem, in kernels build Monday and yesterday. I get a kernel panic when while booting, I don't know how to capture the boot messages to a file (do you) so I can not post them but this is the line that it dies on: panic: ahc0: brkadrint, scratch or SCB Memory Parity Error at seqaddr=0x0 my machine initializes ahc0 with this line earlier in the boot: ahc0 port 0xe800-0xe8ff mem 0xfebce000-0xfebcefff irq 10 @ device 15.0 on pci0 there is a similar line for ahc1. My kernel from 12/12/99 reports this: ahc0: <Adaptec aic7895 Ultra SCSI adapter> irq 10 at device 15.0 on pci0 ahc0: aic7895 Wide Channel A, SCSI Id=7, 255 SCBs ahc1: <Adaptec aic7895 Ultra SCSI adapter> irq 11 at device 15.1 on pci0 ahc1: aic7895 Wide Channel B, SCSI Id=7, 255 SCBs Does anyone have a workaround?
