I know this is a bit short of what you like, but I'm not well set up to
a) record stuff manually; can't read my own writing
b) use a remote console
c) record to floppy, swap partition etc. If someone needs this, mail me
the patch and I will make it good;-)

However, it did seem pretty definite. about stopping;-((
Does not seem likely to me to work for anyone.

Note: I compiled with gcc 2.95-2.

Hardware:
PII-233 on ASUS P2L97-S. Not overclocked. 192 Mb RAM. There is no printer
connected to my parallel port.

Here is part of the dmesg display from my pre6 kernel (that works). I
include it so I can point out where -pre8 gets to.

The 0x378 messages I've marked(*) do not appear.
The second parport0 message os the last that appears before the oops & its
associated messages.

parport0: cpp_daisy: aa5500ff(38)
parport0: assign_addrs: aa5500ff(38)
parport0: cpp_daisy: aa5500ff(38)
parport0: assign_addrs: aa5500ff(38)

After the second parport0 message; I get
Unable to handle kernel NULL pointer dereference at 0..01c.

Notes:
I do not have a printer connected to this machine.
If the person looking at this wants the full text of the oops, quickest to
mail me the patch to apply.
