I can confirm the same behaviour on my nc8230
Comment 2 Dave Jones 2006-10-16 13:30:51 EDT
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.

I installed the new kernel
$ uname -a
Linux goedel.home.rtfm.gr 2.6.18-1.2200.fc5 #1 Sat Oct 14 16:59:26 EDT 2006 i686
i686 i386 GNU/Linux

but I have the same symptoms with the new kernel

After further testing, when suspending with the proprietary ATI driver kernel
module, on resume the keyboard responds (Caps lock works - Alt-SysRq- Reboot occurs)
However no video output occurs
Comment 5 Dave Jones 2006-11-24 15:57:26 EST
Unfortunately, there's rarely anything we can do with proprietary drivers.
You may be able to coax it back to life with some magical incantation of
vbetool, but it's completely black magic.

Good to know the keyboard is back though. I'll close this out, as there's
nothing further we can do.
Comment 6 E. Lefty Kreouzis 2006-11-24 16:04:57 EST
Without the proprietary drivers I don't even get this far.....
No keyboard no screen
