Since 2.4.19-ac1 I occasionally (like 1 in 3 times) see an Oops while
shutting down, containing the line
kernel BUG in apm.c:899
This is an Abit VP6 dual board, with a via chipset. Below you'll find
lspci, (limited) dmesg, and .config information.
Is it really necessary to copy the entire oops by hand, or is this proof
enough that the change in ac1 to enable Asus board to boot is now biting
me?
Kind regards,
Jurriaan

Basically its oopsing because it was about to make an APM call on a
processor other than CPU#0 (physical id), it set the cpus_allowed mask
to CPU#0 only and then rescheduled but ended up on a CPU that was not
CPU#0. Thats because its not making the right and proper calls for the
O(1) scheduler - Willy's patch I merged is right - but not for -ac.
I'll fix that in -ac5.
It should be enough to swap
current->cpus_allowed = 1;
with
set_cpus_allowed(current, 1 << cpu_logical_map(0));
in that file
