Hi all.

First off, Iam a scsi newbie under FreeBSD, used for the last 3 years fbsd
as workstation and as server with IDE devices only.

These are mine scsi hd's:
da0 at ahc0 bus 0 target 0 lun 0
da0: <SEAGATE ST52160N 0344> Fixed Direct Access SCSI-2 device
da0: 10.000MB/s transfers (10.000MHz, offset 15)
da0: 2069MB (4238282 512 byte sectors: 255H 63S/T 263C)
da1 at ahc0 bus 0 target 1 lun 0
da1: <QUANTUM FIREBALL ST3.2S 0F04> Fixed Direct Access SCSI-2 device
da1: 10.000MB/s transfers (10.000MHz, offset 15), Tagged Queueing Enabled
da1: 3118MB (6385696 512 byte sectors: 255H 63S/T 397C)
da2 at ahc0 bus 0 target 5 lun 0
da2: <QUANTUM FIREBALL ST3.2S 0F04> Fixed Direct Access SCSI-2 device
da2: 10.000MB/s transfers (10.000MHz, offset 15), Tagged Queueing Enabled
da2: 3118MB (6385696 512 byte sectors: 255H 63S/T 397C)

This is the controller:
ahc0: <Adaptec 2940A Ultra SCSI adapter> port 0x6000-0x60ff mem
0xe4000000-0xe4000fff irq 15 at device 8.0 on pci0
aic7860: Ultra Single Channel A, SCSI Id=7, 3/253 SCBs

The hardware before i got it was used for win 3.11 and 95, it worked fine
then and now. After my first manualy /etc/periodic/weekly/310. the message
bellow rolled into the console and into /var/log/messages:

(da1:ahc0:0:1:0): SCB 0x9 - timed out
ahc0: Dumping Card State in Message-in phase, at SEQADDR 0x1b1
ACCUM = 0xc0, SINDEX = 0x3, DINDEX = 0x8c, ARG_2 = 0x0
HCNT = 0x0 SCBPTR = 0x1
SCSISEQ = 0x12, SBLKCTL = 0x0
 DFCNTRL = 0x0, DFSTATUS = 0x29
LASTPHASE = 0xe0, SCSISIGI = 0xe6, SXFRCTL0 = 0x88
SSTAT0 = 0x7, SSTAT1 = 0x3
STACK == 0x15a, 0x0, 0xf9, 0xfb
SCB count = 250
Kernel NEXTQSCB = 48
Card NEXTQSCB = 246
QINFIFO entries: 246
-- SNIP --

After i put the Adaptec card and the drives into the compaq system it came
out in the first place, i wasn't able to reproduce the error/debug output.

I don't know anything about the scsi subsystem of fbsd, let alone howto
debug the error output, only of those ide controllers and devices under
fbsd i can handle. Iam using this scsi hardware setup to handle my www.
.org server (no highprofile) for safety iam using the compaq now as www.
server (it's just a plain p133mhz plus 32mb, it works fine)

Is this (error)/output something i should worry about?
