I am experiencing what I suspect is the the same issue running
kernel-2.6.14-1.1637_FC4smp.

Please have a look at Bug #173631.
Comment 2 Alan Miller 2006-04-06 05:17:08 UTC 
I cant install fedora on a DELL 1600Sc poweredge.
Older redhat install fine and sees the correct megadriver for the raid array, 
however redora does at the druid stage when it can see any drives in which to 
write to.

Strange how older code works but newer release doesnt !

Comment 3 Dave Jones 2006-10-16 19:44:39 UTC 
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.

Thank you.

Closing due to inactivity.  Please reopen or file a new report if you continue
to have problems with current Fedora kernels.
