The AHA-2940UW in question is 2 years old at least and it doesn't seem to have anything to do with load on the hard disks. sd1(ahc0:2:0): SCB 0x6 - timed out while idle, LASTPHASE == 0x1, SCSISIGI == 0x0 SEQADDR = 0x5 SCSISEQ = 0x12 SSTAT0 = 0x5 SSTAT1 = 0xa Ordered Tag queued Ordered Tag sent sd1(ahc0:2:0): SCB 0x6 - timed out while idle, LASTPHASE == 0x1, SCSISIGI == 0x0 SEQADDR = 0x5 SCSISEQ = 0x12 SSTAT0 = 0x5 SSTAT1 = 0xa sd1(ahc0:2:0): Queueing an Abort SCB sd1(ahc0:2:0): Abort Message Sent sd1(ahc0:2:0): SCB 6 - Abort Tag Completed. sd1(ahc0:2:0): no longer in timeout --Few days pass-- sd1(ahc0:2:0): SCB 0x2 - timed out in command phase, SCSISIGI == 0x84 SEQADDR = 0x4e SCSISEQ = 0x12 SSTAT0 = 0x7 SSTAT1 = 0x2 Ordered Tag queued sd1(ahc0:2:0): SCB 0x1 timedout while recovery in progress sd1(ahc0:2:0): SCB 0x3 timedout while recovery in progress sd1(ahc0:2:0): SCB 0x7 timedout while recovery in progress sd0(ahc0:0:0): SCB 0x4 timedout while recovery in progress sd1(ahc0:2:0): SCB 0x2 - timed out in command phase, SCSISIGI == 0x84 SEQADDR = 0x4e SCSISEQ = 0x12 SSTAT0 = 0x7 SSTAT1 = 0x2 sd1(ahc0:2:0): abort message in message buffer sd1(ahc0:2:0): SCB 7 - Abort Tag Completed. sd1(ahc0:2:0): no longer in timeout Ordered Tag sent sd1(ahc0:2:0): SCB 0x2 - timed out while idle, LASTPHASE == 0x1, SCSISIGI == 0x0 SEQADDR = 0x4 SCSISEQ = 0x12 SSTAT0 = 0x5 SSTAT1 = 0xa sd1(ahc0:2:0): Queueing an Abort SCB sd1(ahc0:2:0): Abort Message Sent sd1(ahc0:2:0): SCB 2 - Abort Tag Completed. sd1(ahc0:2:0): no longer in timeout This machine has been up for 54 days and this has happened three times since it was rebooted. I thought it might just be due to a crappy choice of hard disks, too. I still need to get around to replacing them and seeing if it helps. > On May 10, 6:13pm, Andrew Maltsev wrote: > > Subject: SCSI problems? > > I'd just done `make world' and upgraded the kernel to -stable (as of > > 9-May). > > > > Here is what I got near the and of booting: > > sd0(ahc0:4:0): SCB 0x2 - timed out while idle, LASTPHASE == 0x1, SCSISIGI == > 0x0 > > SEQADDR = 0x8 SCSISEQ = 0x12 SSTAT0 = 0x0 SSTAT1 = 0xa > > Ordered Tag queued > > sd0(ahc0:4:0): SCB 0x1 timedout while recovery in progress > > sd0(ahc0:4:0): SCB 0x0 timedout while recovery in progress > > sd0(ahc0:4:0): SCB 0x2 - timed out while idle, LASTPHASE == 0x1, SCSISIGI == > 0x0 > > SEQADDR = 0x8 SCSISEQ = 0x12 SSTAT0 = 0x0 SSTAT1 = 0xa > > sd0(ahc0:4:0): Queueing an Abort SCB > > sd0(ahc0:4:0): Abort Message Sent > > sd0(ahc0:4:0): SCB 2 - Abort Tag Completed. > > sd0(ahc0:4:0): no longer in timeout > > Ordered Tag sent > > > > I see no more such messages.
