Here is the Oops:
Options used: -V (default)
-o /lib/modules/2.2.10/ (default)
-k /proc/ksyms (default)
-l /proc/modules (default)
-m /usr/src/linux/System.map (default)
-c 1 (default)
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.

Ok, and here is my configuration (a few maybe relevant parts):
# Loadable module support
#
CONFIG_MODULES=y
CONFIG_MODVERSIONS=y
CONFIG_KMOD=y
#
# General setup
#
CONFIG_NET=y
CONFIG_PCI=y
# CONFIG_PCI_GOBIOS is not set
# CONFIG_PCI_GODIRECT is not set
CONFIG_PCI_GOANY=y

CONFIG_PCI_OLD_PROC=y
CONFIG_APM=y

CONFIG_APM_DO_ENABLE=y
CONFIG_APM_CPU_IDLE=y
CONFIG_APM_DISPLAY_BLANK=y
CONFIG_APM_POWER_OFF=y
CONFIG_APM_IGNORE_MULTIPLE_SUSPEND=y
CONFIG_APM_IGNORE_SUSPEND_BOUNCE=y
CONFIG_APM_RTC_IS_GMT=y
CONFIG_APM_ALLOW_INTS=y
CONFIG_BLK_DEV_CMD640=y
# CONFIG_BLK_DEV_CMD640_ENHANCED is not set
# CONFIG_BLK_DEV_CMD646 is not set
Also, the IDE controller (CMD646 type, seemingly) loses interrupts
from time to time. This problem has gotten worse in later kernels. I
have never in any 2.2.x kernel been able to enable the CMD646 support
marked "EXPERIMENTAL" without the kernel panicking at boot time. If
wanted, I can try to record a kernel oops for that to, but up to now
at least the usual CMD640 support worked more or less fine.
