i am having probs with my system.  I have:

FreeBSD 2.2.1-RELEASE
ahc0 <Adaptec 2940A Ultra SCSI host adapter> rev 1 int a irq 10 on pci0:10
ahc0: aic7860 Single Channel, SCSI Id=7, 3 SCBs
(ahc0:6:0): "QUANTUM FIREBALL ST4.3S 0F0C" type 0 fixed SCSI 2
sd0(ahc0:6:0): Direct-Access 4136MB (8471232 512 byte sectors)
(ahc0:1:0): "MATSHITA CD-ROM CR-504 ST23" type 5 removable SCSI 2
cd0(ahc0:1:0): CD-ROM cd present [332512 x 2048 byte records]

The problem is, sometime my drive locks up for no apparent reason.  the
error i get which doesn't even get logged in /var/log/messages is:

sd0(ahc0:6:0): timed out while idle
SEQADDR = = 0x6
sd0(ahc0:6:0): abort SCB

or something like that.  I had to write it down because the log files had
no records of this.  The system was locked up where i had to use the reboot
button.  Once i rebooted the SCSI bios check could not find my HD.  only
until i did a cold boot did the controller find the HD.  It booted up with
some errors but it came up.  This happend three times so far in about a
week and a half.

I checked the mail archives and found similar probs but no real solutions.  

please email me at:

thanks in advance.
