I can't tell if this is a driver problem, or a hardware problem.
1) Things attached to the SCSI bus don't seem to always work correctly.
a) The tape drive has decided to not back up any files under a
version of Amanda that has worked flawlessly for almost six
months. The error on the system log is one about "unable to get
size". It's almost like an ioctl went away during the
b) The CD-R will not write a CD - I can get into specifics
later, but right now, the problem is the ASC/ASCQ set is
0x89/0x00. I've sent an E-Mail to Sony to get this vendor
specific ASC, but the drive and 'cdrecord' are reported to work
together in 1.2.
c) The 'parent' directory or the 'current' directory will
sometimes disappear. Using 'cd' to change to a known directory
will work, after which point the problem is not reproducable.
This only happens on sd0. None of the IDE drives ever exhibit
d) Some of my CD-ROM drives will just disappear. They will
probe OK, but once I try to access them, either the files on the
drive aren't there, or the drive will suddenly stop working and
the mount point will become a 'regular file'. After I reboot,
they might work fine the next couple of times.
2) The latest kernel will not recognize the 'uha' card when a kernel
from a week ago will. I deleted the libraries and the destination
directory for the kernel build, and it doesn't help. Even COLD booting
the system (which would work if the card were in an 'indeterminate state'
3) I've not been able to get a 'known working' Adaptec 1542 to work in
the machine in several weeks. I tried to get it working the other
night, but it fails the probe for the drives.
I've checked termination on the SCSI chain, and tried reducing the drive
count (from 6 to 3) to see if the SCSI bus was overloaded. Neither of
those yielded any positive results. I only have the one Ultrastor, or
I'd try replacing that.
I have SCSI verbose turned on, but I have yet to be able to figure out
any more from the output than I knew before.
