The following reply was made to PR i386/22640; it has been noted by GNATS.

We have caught in mysterious SCSI trouble just like yours. OS is FreeBSD 3.5.1-RELEASE, and host adapter is adaptec 2940UW, and disks are IBM 18G ultrastor, DNES-318350. suddenly died twice in a week, a disk obstinately kept "being accessed" LED on. I tried hot start without power down, but did not work - the machine tried to boot as if it had no disk. on second time, after success of booting with power cycle, I examined it under single-user mode. on the first time it equipped two same disks, but this time, only one drive was attached, SCSI-IDfied as #1, da0, which is devided into 2 partitions and a swap region. the secondary filesystem (da0s1e for /home), which was pretty heavily accessed mostly for MRTG logging and graphing, was awfully corrupted. the primary one (da0s1a for /) was not corrupted at all. in /var/log/dmesg.yesterday, I found following message: I don't know when it was printed - sorry serial console. (da0:ahc0:0:0:0): SCB 0x3e - timed out while idle, LASTPHASE == 0x1,\(wrap) SEQADDR == 0x153 (da0:ahc0:0:0:0): SCB 62: Immediate reset. Flags = 0x4040 (da0:ahc0:0:0:0): no longer in timeout, status = 34b ahc0: Issued Channel A Bus Reset. 64 SCBs aborted anyone knows how to track/examine this "bug", or hardware/firmware failure or any other SCSI boodoo? ---- Wataru Satoh <wataru-s@mfeed.ad.jp> / INTERNET MULTIFEED CO.
