Last modified: 2007-11-30 17:11:29 EST
Description of problem:
Unable to load the p4_clockmod kernel module
Version-Release number of selected component (if applicable):
Linux poseidon 2.6.16-1.2080_FC5 #1 Tue Mar 28 03:38:34 EST 2006 i686 i686 i386
Steps to Reproduce:
1. modprobe p4_clockmod
FATAL: Error inserting p4_clockmod
No such device
Modprobe loads the p4_clockmod kernel module.
Loading the p4_clockmod kernel module worked successfully on FC4 before an
upgrade to FC5 (ie 2.6.15-1.1833_FC4-i686).

A new kernel update has been released (Version: 2.6.18-1.2200.fc5)
based upon a new upstream kernel release.
Please retest against this new kernel, as a large number of patches
go into each upstream release, possibly including changes that
may address this problem.
This bug has been placed in NEEDINFO state.
Due to the large volume of inactive bugs in bugzilla, if this bug is
still in this state in two weeks time, it will be closed.
Should this bug still be relevant after this period, the reporter
can reopen the bug at any time. Any other users on the Cc: list
of this bug can request that the bug be reopened by adding a
comment to the bug.
In the last few updates, some users upgrading from FC4->FC5
have reported that installing a kernel update has left their
systems unbootable. If you have been affected by this problem
please check you only have one version of device-mapper & lvm2
installed. See bug 207474 for further details.
If this bug is a problem preventing you from installing the
release this version is filed against, please see bug 169613.
If this bug has been fixed, but you are now experiencing a different
problem, please file a separate bug for the new problem.
The p4_clockmod module now loads with more recent kernels, although with
limited functionality. See https://bugzilla.redhat.com/bugzilla/
I'll work on that bug for the next update.
