FYI, I just had it *after* boot, i.e. some 30 seconds after the swsusp 
resume (trace below), and _again_ _after_ I warm-rebooted the machine using
SysRq+B. The subsequent warm-reboot went OK.

Linux 2.4.21 + ACPI 20030619

ksymoops 2.4.9 on i686 2.4.21-xacs.  Options used
     -V (default)
     -k /proc/ksyms (default)
     -l /proc/modules (default)
     -o /lib/modules/2.4.21-xacs/ (default)
     -m /usr/src/linux/System.map (default)

Warning: You did not tell me where to find symbol information.  I will
assume that the log matches the kernel and modules that are running
right now and I'll use the default options above for symbol resolution.
If the current kernel and/or modules do not match the log, you can get
more accurate output by telling me the kernel version and where to find
map, modules, ksyms etc.  ksymoops -h explains the options.

[the kernel is tainted by swsusp and pctel module, but it shouldn't really
 matter since this oops happens mainly at boot]

I'll have yet to see if it still happens with 2.4.22.
