I've been getting system hangs - everything locked up, no interrupts, etc. Each reboot is followed by a dump from the ahc, this being the last one: (da2:ahc0:0:3:0): SCB 0x6 - timed out ahc0: Dumping Card State while idle, at SEQADDR 0x9 ACCUM = 0x4, SINDEX = 0x64, DINDEX = 0x65, ARG_2 = 0x3 HCNT = 0x0 SCSISEQ = 0x12, SBLKCTL = 0x6 DFCNTRL = 0x0, DFSTATUS = 0x89 LASTPHASE = 0x1, SCSISIGI = 0x0, SXFRCTL0 = 0x80 SSTAT0 = 0x20, SSTAT1 = 0xb STACK == 0x3, 0x17b, 0x165, 0x0 SCB count = 20 Kernel NEXTQSCB = 5 Card NEXTQSCB = 5 QINFIFO entries: Waiting Queue entries: Disconnected Queue entries: 0:14 3:9 1:6 QOUTFIFO entries: Sequencer Free SCB List: 2 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 Pending list: 14, 9, 6 Kernel Free SCB list: 8 15 16 17 18 19 0 1 2 3 4 7 13 12 11 10 Untagged Q(3): 6 sg[0] - Addr 0xf884880 : Length 8 (da2:ahc0:0:3:0): Queuing a BDR SCB (da2:ahc0:0:3:0): Bus Device Reset Message Sent (da2:ahc0:0:3:0): no longer in timeout, status = 34b ahc0: Bus Device Reset on A:3. 1 SCBs aborted da2 at ahc0 bus 0 target 3 lun 0 da2: <iomega jaz 1GB J.86> Removable Direct Access SCSI-2 device da2: 10.000MB/s transfers (10.000MHz, offset 15) da2: 1021MB (2091050 512 byte sectors: 64H 32S/T 1021C) The first critical question for this list is whether this is just the card recovering from a system freeze, or is this an indication that I've got problems in my SCSI subsystem somewhere. The second one is, if there are problems in the SCSI system, what are they? Or, more likely, what more information is needed before that can be determined.
