Comment 1 Rahul Sundaram 2006-02-20 10:50:34 UTC

These bugs are being closed since a large number of updates have been released
after the FC5 test1 and test2 releases. Kindly update your system by running yum
update as root user or try out the third and final test version of FC5 being
released in a short while and verify if the bugs are still present on the system
.Reopen or file new bug reports as appropriate after confirming the presence of
this issue. Thanks

Comment 2 Glen 2006-08-21 06:46:18 UTC
Created attachment 134549 [details]
output of dmesg

Comment 3 Glen 2006-08-21 06:48:24 UTC
As you can see in the file I just attached, I'm still having problems when I
fire up FC6 test2.

Comment 4 Dave Jones 2006-10-16 20:49:00 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.

Comment 5 Glen 2006-11-01 06:27:28 UTC
So I just tried FC6 and it doesn't even recognize my hard disk now.  And maybe
I'm missing something, but I sure as heck can't figure out how to load drivers
for my SCSI controller.  Has that feature been removed?

Comment 6 Dave Jones 2006-11-21 00:16:46 UTC
should still be there, though I forget how to invoke it..  you may need to boot
with 'noprobe'.

Comment 7 petrosyan 2008-03-11 00:09:29 UTC
Fedora Core 5 and Fedora Core 6 are no longer maintained. Is this bug still
present in Fedora 7 or Fedora 8?

Comment 8 Jon Stanley 2008-03-31 18:31:20 UTC
Removing NeedsRetesting from whiteboard so we can repurpose it.
