I have been getting the above as well, and I also get EXT2-fs error
(device 08:11): ext2_check_inodes_bitmap: Wrong free inodes count in
super block, stored = 1049521, counted = 1049519.  The machine just will
not run for very long before some scsi problem kills it, sometimes it
tries to reset and hangs, sometimes it just locks solid with no messages
logged or on the screen.  I have disabled disconnects and wide
negotiation with no luck, what else can I try?

The bios version on the Adaptec card is 1.32 and it seems the problems
started as soon as I added additional HD's.  When this happened I
recompiled the kernel with the 5.0.18 drivers with no success in regards
to fixing the problems.  Could the Quantums somehow be the problem even
though I see others having problems with other drives?

The stats for my system are listed below.
