Hello,
according to "oops-tracing.txt", I send you this problem report.
This is a problem I have been experiencing with all kernels I have
tried later than 2.6.11.12, currently with 2.6.13.4. I am using the
Slackware 10.2 distribution.
The system is working normally and completely stable. When I shutdown
or restart, however, I have the following message:

[/code]
Before, it says something about a segmentation fault in line 54 of rc.6.
I have tracked this down to the following command in line 44:
[code] if ! grep -q -w rtc /proc/ioports ; then[/code]
and a simple [code]cat /proc/ioports[/code] gives me a segmentation
fault every time.
I have read on the kernel mailing lists that this is due to drivers
not properly unloading, so I won't post an lsmod.
Thanks for your attention,
