SubjectOops with 2.4.4-ac7
Hi,

the following oops happened with kernel 2.4.4-ac7.

The motherboard (Micron PTSAM-04. It's a dual board but I only have one
processor running a UP kernel) is unfortunately not completely above
suspicion, although it has not caused problems in the past ...
In order to get the kernel to boot at all I have to prevent the on-board
Samurai IDE chip from being initialized which I do by setting MAX_HWIFS to 2
in include/asm/ide.h (this has worked fine for nearly two years now).

Let me know if the oops is interesting and you need more info.

Greetings

Robert

ksymoops 2.4.1 on i686 2.4.4-ac7-PII. Options used
-V (default)
-k /proc/ksyms (default)
-l /proc/modules (default)
-o /lib/modules/2.4.4-ac7-PII/ (default)
-m /lib/modules/2.4.4-ac7-PII/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.

No modules in ksyms, skipping objects
Warning (read_lsmod): no symbols in lsmod, is /proc/modules a valid lsmod file?
