[Click] [click] occuring segmentation fault in cilck-install

[Jason Haas]

I actually have a vanilla 2.6.13.2, patched kernel running a CVS version
downloaded on Jan. 17th.  It's a Fedora Core 3 machine.  I have two other
machines (both vanilla 2.6.13.2 + click patch), one SuSE 9.1-pro and one FC4
that don't work.  The funny thing is, that even though there are errors on
insertion, the configurations run correctly, but upon trying to uninstall
them, the kernel seg faults.  I've tried copying the .config for the kernel
from the working machine to one of the broken ones, but it doesn't boot
then.

Here's the relevant dmesg for insert (from running test.click):

mtrr: base(0xe8020000) is not aligned on a size(0x800000) boundary

I too would appreciate any help, if anyone knows why one might work and
another not.

Thanks,
