So you mean that this bug is squished in 2.4.22 then?
Anyway I got an oops-trace ran through ksymoops by the
customer and here is the result (If anyone is interested anymore....)
ksymoops 2.4.9 on i686 2.4.20-20.9. Options used
-V (default)
-k /proc/ksyms (default)
-l /proc/modules (default)
-o /lib/modules/2.4.20-20.9/ (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.
Error (expand_objects): cannot stat(/lib/ext3.o) for ext3
Error (expand_objects): cannot stat(/lib/jbd.o) for jbd
Error (expand_objects): cannot stat(/lib/aacraid.o) for aacraid

Error (expand_objects): cannot stat(/lib/scsi_mod.o) for scsi_mod
Error (regular_file): read_system_map stat /usr/src/linux/System.map failed
Warning (map_ksym_to_module): cannot match loaded module ext3 to a unique
module object. Trace may not be reliable.
Warning (map_ksym_to_module): cannot match loaded module aacraid to a unique
