Summary: 2.6.1-mm1 gives an OOPs while doing a modprobe. Subsequent
references to /proc/modules hang (causing hangs while doing a 'shutdown'
because of scripts trying to rmmod modules. lsmod and 'cat /proc/modules'
hang as well after the oops.
This one's from trying to load ip_conntrack_ftp:
Module len 6897 truncated

printing eip:

My original thought was that the ip_conntrack_ftp.ko got corrupted,
but the 6978 is the same size as it's been since at least 2.6.0-mm2,
and this oops is *after* I'd hit one and done an 'rm -rf /lib/modules/2.6.1-mm1'
and 'make modules_install'. And it isn't just ip_conntrack_ftp:
(this time, while trying to 'modprobe aes':

Yes, this one's nvidia-tainted, the other one wasn't, so it isn't nvidia ;)
Any ideas?

My original thought is about Rusty.
The `check for truncated module' patch is clearly triggering when it should
not be. It then incorrectly returns "success" from load_module() even
though load_module() failed.
A `patch -R' of
ftp://ftp.kernel.org/pub/linux/kernel/people/akpm/patches/2.6/2.6.1/2.6.1-mm1/broken-out/check-for-truncated-modules.patch
should fix it up.

Hey cool,
I build the 2.6.2-mm1 and just got the same problem with the modules, went out
for lunch and now works fine again.
