Sean's cdrom isn't being probed by the scsi driver (thus no mounts). Sean has two scsi controllers (I assume on board), ach0 and ahc1. In May, the cdrom showed up: May 11 03:10:56 user2 /kernel: cd0 at ahc1 bus 0 target 4 lun 0 May 11 03:10:56 user2 /kernel: cd0: Removable CD -ROM SCSI-2 device May 11 03:10:56 user2 /kernel: cd0: 5.813MB/s transfers (5.813MHz, offset 15) May 11 03:10:56 user2 /kernel: cd0: Attempt to query device size failed: NOT REA DY, Medium not present But, in June it is gone: Jun 10 00:50:15 user2 /kernel: da1 at ahc1 bus 0 target 1 lun 0 Jun 10 00:50:15 user2 /kernel: da1: Fixed Direct Access S CSI-2 device Jun 10 00:50:15 user2 /kernel: da1: 11.626MB/s transfers (5.813MHz, offset 8, 16 bit), Tagged Queueing Enabled Jun 10 00:50:15 user2 /kernel: da1: 8715MB (17850000 512 byte sectors: 255H 63S/ T 1111C) Jun 10 00:50:15 user2 /kernel: da0 at ahc1 bus 0 target 0 lun 0 Jun 10 00:50:15 user2 /kernel: da0: Fixed Direct Access S CSI-2 device Jun 10 00:50:15 user2 /kernel: da0: 11.626MB/s transfers (5.813MHz, offset 8, 16 bit), Tagged Queueing Enabled Jun 10 00:50:15 user2 /kernel: da0: 8715MB (17850000 Sean says that the scsi BIOS sees the drive, and doesn't think there is a cabling problem. I'm scratching my head a bit here. Certainly the first priority is fixing whatever happened between May 11 and June 10 -- get the drive to be probed. I'm thinking improper termination at this point. This isn't always a deal breaker (in fact, I accidently ran my cdrom with bad termination for a few months without realizing it). Sean: could you please let us know the order the devices are on the chain. Also, please doublecheck the termination of all devices. I'm sure you've been over this a couple of times by now, but the problem is most certainly HW (IMHO of course).
