SCSI Error Msgs (Linux, 2.0.33, Adaptec 2940UW)

[Tom Browder]

I have a DEC Alpha with Adaptec 2940 UW SCSI
host adapter, two SCSI hard drives, and a SCSI
tape (HP DAT).  The Adaptec hosts etttings are the default
ones. While making a tape backup (using tar)
I get the following messages:

Mar 23 11:06:24 mimi kernel: EXT2-fs error (device 08:02): ext2_find_entry: bad entry in directory #221368: directory entry across blocks - offset=0, inode=3302255, rec_len=25456, name_len=50

Mar 23 11:06:44 mimi kernel: (scsi0:0:0:0) Abort called for already completed command.

The system basically hung and wouldn't respond to a login, so
I did a hard reboot without a graceful shutdown:

Can anyone suggest a configuration change or
other correction to fix the problem (there are
new SCSI selections for the Adaptec 2940 which
are not documented in the INSTALL help)?

Thanks.
