I've discovered a repeatable kernel freeze in v2.2.1. When the freeze
occurs, switching between VCs is possible, but no commands can be
run. The scroll-lock keycombos does work.
When running in X, the screen gets garbled.

The freeze happens when I tried to run cdparanoia on a CD-ROM that
seems to lack CDDA capabilities. It's an old SCSI drive, connected to
a AHA1542CF ISA adapter (BIOS v2.10).

I've tried to capture some of the output coming from both cdparanoia
and strace, attached below.

Please reply in personal mail too, as I'm reading linux-kernel through
a NG with bad throughput.

cdparanoia was run as a normal user with full access to sga.

Just before the freeze, this message (drivers/scsi/aha1542.c:553) is
printed:
Wrong buffer length supplied for request sense (256)
