Often, when mounting a CD-Rom on my SCSI CD-Rom drive I, rather than getting
a proper mount, get something like this:
-r-xr-xr-x 1 root root 0 Dec 31 1969 8*
Note that 8 is the mount point (ie a directory), yet after mounting it shows
up as an executable file. The messages logged during the mount operation
show nothing out of the usual. Usually unmounting, ejecting, and remounting
solves this although occasionally it takes two or three tries. The drive
works fine once it has been successfully mounted. Note that the only
CD-Roms I generally use are CD-R's. I don't know if this has any relevance.
This has occured to me both on 2.0.30 and 2.0.31. The drive is a Toshiba
XM-3801TA SCSI drive attached to a generic NCR 810a based SCSI board. Also
on the the chain are a Seagate Barracuda (ST32550N) and a Nakamichi MBR-7 7
disk changer. Also in the machine is an NCR 875 with a Quantum IMP 2100S
drive and a Philips(IMS) CDD-2000 CD recorder. This happens consistenty
with the 2.5* and 2.6* ncr53c8xx "FreeBSD-port" drivers. The SCSI buses are
set to operate at 10MB/sAny ideas? I've attached the output of the various
proc files at the end.
As a side note, the Barracuda(firmware revision 0022) is on the 810 because
when attached to the 875 I get bus timeouts/crashes similar to those
described by someone else recently on this list(aborting command due to
timeout messages a few times followed by a complete scsi bus reset etc), but
my problems weren't solved by an upgrade to the 2.6 driver. I've tried
multiple cables and have disabled command qeueing but not disconnection.
However, while I had at one point another Barracuda which worked fine on the
875, I'm not 100% confident that there isn't some weird jumpering problem
somewhere on my chain so...(I need to go read up to learn about the
different types of termination etc...the drives tend to have a jumpers for
things which mean nothing to me. :) ).
