>Environment:
PPro 200, 128MB ram, five 4GB disks (one quantum, four barracudas...
the quantum has been upgraded). Adaptec PCI SCSI card as shown
below.
Probing for devices on PCI bus 0:^M
chip0 Intel 82440FX (Natoma) PCI and memory controller rev 2 on pci0:0^M
chip1 Intel 82371SB PCI-ISA bridge rev 1 on pci0:1:0^M
chip2 Intel 82371SB IDE interface rev 0 on pci0:1:1^M
ahc0 Adaptec 2940 Ultra SCSI host adapter rev 0 int a irq 12 on pci0:9^M
ahc0: aic7880 Wide Channel, SCSI Id=7, 16 SCBs^M
ahc0 waiting for scsi devices to settle^M

>Description:
We get a consistant panic every 8 or so hours. It goes something like:
ahc0:A:0: no active SCB for reconnecting target - issuing ABORT^M
SAVED_TCL == 0x20^M
panic: ahc0:A:0: Target did not send an IDENTIFY message. LASTPHASE = 0x0, SAVED
_TCL == 0x10
The only real custom config that might apply is that four of the disks
are striped with ccd. The machine is a very heavily used nntp reader
machine, with lots of disk I/O.
>How-To-Repeat:
The machine panics every so often. I cannot force the panic to occur with
any particular sequence of commands.
We are currently running an older kernel (Feb 25 kernel, CTMs through 286)
to determine if the Feb 26 ctm patch (src-2.1.0287) is the cause of
the panic. We will not know the answer for another day or two.
