[1]. OOPS on boot when using loadlin 1.6a directly after exiting Win95.
[2]. When booting into a 2.2.10 kernel, just after "PPP line dicipline
registered", the below OOPS is produced. It's easily repeated on this
machine.
[3]. Keywords: OOPS boot loadlin
[4]. Linux version 2.2.10 (root@localhost.localdomain) (gcc version
2.7.2.3) #9 Sun Jun 27 15:26:40 PDT 1999
[5]. (Be aware that this is generated from hand-typed info... this
happens before klogd is up. Anything that looks REALLY, REALLY wrong
(other than the existance of this report) is quite likely my fault.

[7.5] This only happens when booting in directly from Windows (via a
shortcut set to enter DOS mode and run loadlin). It may be worth noting
that Windows engages the SB Live's DOS emulation before calling loadlin
(but I don't have the linux drivers starting on boot, so this shouldn't
be a problem).
