Subject1.3.94 problems

Since no-one's bothered to reply to my questions about likelihood of
hardware problems causing the oopses I've posted, I'll continue to post
oopses as I get them.

Other 1.3.94 problems I've found include a large number of unresolved
symbols (every module I compiled in fact), and the failure of affs to
compile (a module option for this would be nice).

Running sdoom on the console still reliably freezes the dumb terminal
attatched to ttyS2 (2nd serial card), sometime causing an oops in doom
when you hammer the keyboard on this terminal in its freezed state. Other
console games (abuse for example) cause no such problems.

Kernel 1.3.94, comiled with 2.7.2.l.3, config available...

Sorry, my recently upgraded (2.7.0.12 binutils) objdump is refusing to
disassemble for some reason...

Note that I've seen another oops occuring in the permission syscall under
a recent kernel.

Cheers,
-- Chris.
