SubjectPROBLEM: system hangs on dual 1GHz PIII system with 2.4.13-ac8
PROBLEM: system hangs on dual 1GHz PIII system with 2.4.13-ac8

Full Description:
This system has frequent lockups. Lockups used to occur every few days
or as infrequently as once per two weeks. That was with the early 2.4.x
kernels. Since moving to the latest stable ac-series kernel, the kernel
stayed up two weeks (to the day) before the system hung.

Keywords: SMP, Dual CPU PIII, kernel hang, Paging Request, Virtual Address

Kernel version (from /proc/version):
Linux version 2.4.13-ac8 (root@willscarlet) (gcc version 2.96 20000731
(Red Hat Linux 7.1 2.96-98)) #2 SMP Mon Nov 19 16:05:19 EST 2001

Oops output run through ksymoops:

ksymoops 2.4.1 on i686 2.4.13-ac8. Options used
-V (default)
-k /proc/ksyms (default)
-l /proc/modules (default)
-o /lib/modules/2.4.13-ac8/ (default)
-m /boot/System.map-2.4.13-ac8 (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.

Unable to handle kernel paging request at virtual address 810426b4

ksymoops 2.4.1 on i686 2.4.13-ac8. Options used
-V (default)
-k /proc/ksyms (default)
-l /proc/modules (default)
-o /lib/modules/2.4.13-ac8/ (default)
-m /boot/System.map-2.4.13-ac8 (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.
