Hi... I updated my system last night with make world/make kernel/mergemaster, and the new kernel doesn't seem to work. It sits there for a while at "Waiting for SCSI devices to settle" and then gives the following message. ahc0: Timedout SCB already complete. Interrupts may not be functioning. (probe1:ahc:0:1:0): SCB 0x8 - timed out It then dumps the card state, which I can copy down if needed, but it'll have to be by hand, since I don't have a serial console. An older kernel (May 7th 2003) works fine. The controller is: ahc0: <Adaptec 2940 Ultra SCSI adapter> port 0xd800-0xd8ff mem 0xde000000-0xde000fff irq 15 at device 9.0 on pci0 aic7880: Ultra Wide Channel A, SCSI Id=7, 16/253 SCBs The drives on the card are: da0 at ahc0 bus 0 target 8 lun 0 da0: <IBM DCAS-34330W S65A> Fixed Direct Access SCSI-2 device da0: 40.000MB/s transfers (20.000MHz, offset 8, 16bit) da0: 4134MB (8467200 512 byte sectors: 64H 32S/T 4134C) and cd0 at ahc0 bus 0 target 3 lun 0 cd0: < CD-R/RW RW7060S 1.50> Removable CD-ROM SCSI-2 device cd0: 3.300MB/s transfers The cd-rw drive is external, if that makes any difference. I'm pretty sure my cabling and termination are good, as I've been running in this setup for over a year now without any problems. The motherboard is an ASUS P5A, with an AMD K6-2/500MHz processor. Does anyone have a clue what's wrong, and/or how to fix it? I'm happy to provide any debugging information requested, just tell me what you need and how to get it. Thanks -Adam
