Hi,

This Oops is 100% repeatable in 2.1.128, i386/SMP. When I have the
following modules loaded:

Module Size Used by
BusLogic 34600 0 (autoclean)
sd_mod 17276 0 (autoclean)
scsi_mod 57552 2 (autoclean) [BusLogic sd_mod]
serial 17780 2 (autoclean)
autofs 9544 1 (autoclean)
ipv6 91856 -1 (autoclean)
ne 6384 1 (autoclean)
8390 6080 0 (autoclean) [ne]
ipx 12348 1 (autoclean)
nls_cp437 3548 3 (autoclean)
msdos 8348 3 (autoclean)
fat 24320 3 (autoclean) [msdos]
devpts 3304 1 (autoclean)
unix 10676 20

and I perform:

# rmmod BusLogic
# rmmod sd_mod

then an Oops is generated.

Attached there is the Oops and an edited objdump -S output from sd_mod.o.
The problematic instruction is marked by a series of caret (^)
characters. If anyone can deduce anything useful from this report that
will be great. I may supply other information if needed.

Maciej
