We were tracking -stable, too, so we had to reboot sometimes for a new kernel. (We stopped tracking at 3.1-Release, though). But we still have to reboot sometimes, e.g. when we fiddled with some kernel options or something like that. It happens seldom, but that doesn't matter. This particular box is the server for a bunch of diskless icafe terminals, which are used only during the day. In the evening and at night we can experiment and reboot without interrupting any important service -- BUT it's important that the server comes up again after a reboot without having to travel to the room where it's physically located to press the reset button if necessary. > > > Is this bug known?

By the way, what kind of SCSI devices do you have? Maybe the problem only occurs with some devices. We have: Waiting 5 seconds for SCSI devices to settle sa0 at ahc0 bus 0 target 6 lun 0 sa0: Removable Sequential Access SCSI-2 device sa0: 10.0MB/s transfers (10.0MHz, offset 32) changing root device to da0s1a da0 at ahc0 bus 0 target 0 lun 0 da0: Fixed Direct Access SCSI-2 device da0: 80.0MB/s transfers (40.0MHz, offset 15, 16bit), Tagged Queueing Enabled da0: 4357MB (8925000 512 byte sectors: 255H 63S/T 555C) da1 at ahc0 bus 0 target 1 lun 0 da1: Fixed Direct Access SCSI-2 device da1: 80.0MB/s transfers (40.0MHz, offset 15, 16bit), Tagged Queueing Enabled da1: 4357MB (8925000 512 byte sectors: 255H 63S/T 555C) da2 at ahc0 bus 0 target 2 lun 0 da2: Fixed Direct Access SCSI-2 device da2: 80.0MB/s transfers (40.0MHz, offset 15, 16bit), Tagged Queueing Enabled da2: 4357MB (8925000 512 byte sectors: 255H 63S/T 555C) cd0 at ahc0 bus 0 target 5 lun 0 cd0: Removable CD-ROM SCSI-2 device cd0: 20.0MB/s transfers (20.0MHz, offset 15) cd0: Attempt to query device size failed: NOT READY, Medium not present All of them work fine, once the machine has booted. The DDS3 streamer and the CD-ROM drive are connected to the narrow connector, the HDs are connected to the U2W/LVD one. Cabling and termination is OK.
