It worked fine in a preCAM system exept for timeout errors when using a rewind devicenode. After CAM i get a lookups at probing of the SCSI-bus. I don't get any timeoutmessages or anything. If the powercord to the tapedrive is unplugged the boot continues and the tapedrive is in the report. This is even when the tapedrive stays unplugged. I have tried two version of firmware on the tapedrive 2618 and 2644 for no effekt. If multiple LUN support is enabled (normally off on my system) on the controller (Adaptec 2940UW), the tape driver is reported on all LUNs in the BIOS scan. I thought that maybe multiple LUN probing locked the drive and tried the following patch to sys/cam/cam_xpt.c for no effect. { { T_SEQUENTIAL, SIP_MEDIA_REMOVABLE, "EXABYTE, "EXB-8200*", "*" }, CAM_QUIRK_NOLUNS, /*mintags*/0, /*maxtags*/0 }, Follows part of dmesg with a 15 min wait between lockup and unplugging of powercord to tapedrive and a SCSI_DELAY of 60000. /Johan Oct 3 13:38:44 phoenix /kernel: (noperiph:ahc0 Oct 3 13:38:44 phoenix /kernel: :0:X:X): SCSI bus reset delivered. 0 SCBs aborted.
