I've done my homework on this one. I looked through the mailing list archives, and found a case identical to mine. The errors showing up in the device probe are: ahc0 <Adaptec 2940 Ultra SCSI host adapter> rev 1 int a irq 11 on pci0:17 ahc0: aic7880 Wide Channel, SCSI id=7, 16 SCBs ahc0 waiting for scsi devices to settle ahc0: board is not responding cmd fail (ahc0:0:0): SCB 0x1 timeout while recovery in progress (ahc0:0:0): "unknown unknown ????" type 13 fixed SCSI 0 uk0(ahc0:0:0):unknown This looks like it might be a termination problem, right? So, I tested both automatic and low ON high ON termination settings on the card, and tried multiple devices amd terminators on the external 68-pin connector. I also got this error when no devices were attached. My computer meets the minimal requirements for the card. It's a generic MMX motherboard with a 166 MHz Pentium on it. All PCI slots support bus mastering with no way to turn it on or off. I've tried disabling sync nego, adapter resets, wide nego, and device disconnects, but no joy. I've tried wiring down IRQs to PCI slots in the BIOS. Other PCI devices work fine (VGA and fxp). The 2940UW continuously times out and claims to be discovering a uk at every id. Is there something I can do to fix this? Thanks for any help you give. Joe Clarke To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-questions" in the body of the message
