Hello.
I'm getting this oops while trying to load pcihpacpi. I don't think that I have such thing installed on my IBM Thinkpad. But maybe it is of interest of someone of you.
ksymoops 2.4.5 on i686 2.4.19-rc1. Options used
-V (default)
-k /proc/ksyms (default)
-l /proc/modules (default)
-o /lib/modules/2.4.19-rc1/ (default)
-m /boot/System.map (specified)
