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,

this makes no sense. A driver is not properly doing it's unloading.. to
find out which that is an lsmod is NEEDED .....
unless people on this list are clearvoyant nobody can help you
otherwise...

Does this problem happen without ever loading the vmware modules since
booting?
It it doesn't, please complain to vmware.

This is what I get when I throw out the LVM2 packages
(device-mapper-1.01.04-i486-1.tgz and lvm2-2.01.09-i486-1.tgz):

The address at 03e0-03e1 still looks strange, but no more oopses.
... meaning that the module who produces the problem is dm_mod.
BTW, I have no VGs on my system.
Anything else I can do to help tracking the problem?

Did you perhaps load and unload the (PCMCIA) i82365 driver module?

What's a VG?

It's possible, the machine has a PCMCIA slot I never use.
But I haven't changed anything related to PCMCIA, so the problem
should still be there, but it isn't since I got rid of dm_mod.

A volume group, as used in the context of logical volumes and LVM2.
