--enable-debug doesn't work.  I had to use export CFLAGS=-g before
./configure.  I examined configure.in.  There is no handling there.  Neither
in linux/configure.in nor in another place.  Only ChangeLog.0 mentions that
it have to work from 1994 ;-)

It crashes in kern/queue.c:72 There are functions handling queues.  Bad :(((
It seems that the driver writes where it's not its business.

And there is something else.  The driver says SCSI is not terminated but
Linux doesn't give such a message.  It hangs just after printing it has
loaded 422 instructions... (Linux reports 422 too).

Any ideas before digging the code?
