I had almost no problems at all using a 2940 under 1.2.13 with the Nov 12
1995 driver. (Earlier drivers, esp. before June 26 1995, were quite unstable.)

1.3.84 actually seems a bit less reliable -- every so often the machine
won't boot, complaining about "SCSI timeout" problems. This usually
only happens right after I turn the machine on after it's been cold
for awhile, and rebooting usually fixes the problem. Once it gets
past the bootup sequence, however, it works fine.

I have had occasional lockups (with the Nov 12 driver) when doing
backups to tape. This may be fixed in the 1.3.84 driver.

Note that proper termination is *extremely* important; if you don't
get this right, things will majorly fuck up.
