Hello all,
after checking the archives of this list (as well as freebsd-scsi), i
finally decided to post a problem that i have here.
i hope this is the right place and way to search for advice (and/or help).
I am using FreeBSD 3.0-CURRENT (of today), and have a problem with one of
my scsi-harddisks. /var/log/messages says:
Oct 24 10:00:56 daneel /kernel: (da3:ahc0:0:3:0): SCB 0xe1 - timed out

this message is then repeated for zillions of times (exactly once every
60 seconds), once it has occured once (it occurs for the first time, when
the harddisk is used a bit more heavily). eventually the whole system
hangs (responds to ping, but not to telnet or anything similar, although
the filesystem on the harddisk contains no part of the system, just data
of a samba-fileserver).
first i thought that my harddisk might be dieing, but then i read that
other ppl had similar problems when switching to the CAM driver (when
using 'strange' harddisks, as far as i understood).
i have used this harddisk for quite some time without any problems that i
could notice under 2.2-STABLE. the problem seems to have started exactly
when updating my system to 3.0-CURRENT.
(by the way is there a 3.0-STABLE or will there be sometime soon ?!)
here is the output of dmesg:
