For several releases I keep getting following (or similar) general protection
faults in the APM code while using 'WINE'. My hardware configuration was not
changed in the last 3 months.
The kernel is vanilla 2.1.117, UP, compiled by gcc version 2.7.2.1,
.config is appended below, bootup messages appended below too for more
information. WINE version is 980822, but the crashes happened with 980809 too.
(And I had to replace the printk("scheduling in interrupt\n"); in
kernel/sched.c::schedule() by panic(...), for I kept getting recursive
faults 'scheduling in interrupt, Aieeeeeee' otherwise.)
Copied from paper, symbols resolved from System.map by hand.

This seems to be the end of APM_GET_EVENT macro.
Common to all the GPFs is, that I was running programs under WINE at the
time of the crash. (When not running WINE, the same configuration hums
along happily for days.)
My suspicion is that this is another case of junk left in the FS register
by WINE. However, the stack in the crashdump looks weird too.
The crash is not easily reproduceable, but doing a testrun through my
applications usually triggers it within 10 minutes.
Ciao, Marcus
