Description Billy Allan 2005-09-13 15:36:32 UTC
I applied the YOU update for the kernel.  Now upon picking Xen at boot-time
there is a kernel-panic during boot.  I can obviously fix this manually, but it
seems like YOU should notice & "do the right thing" in the Xen case...
Comment 1 Jiří Suchomel 2005-09-14 06:45:55 UTC
If YOU should do something special (what?) -> mir.
Michael, if it's XEN/kernel problem, reassign to XEN/kernel people.
Comment 2 Michael Radziej 2005-09-14 07:06:15 UTC
Billy, can you please provide logs (tar the complete /var/log/YaST directory)?
What was your configuration? (Did you run it on XEN domain 0, or a different
domain? Which domain crashed?) Please also take a look at the XEN and system
logs if they contain something valuable. Did you get a kernel trace?

@aj: Please check if you consider the severity appropriate.

Comment 4 Billy Allan 2005-09-14 09:44:34 UTC
Hi,

The configuration of the system was pretty much a default install with Gnome +
the developer tools.  I had picked Xen at install-time and booted with the Xen
option from Grub, but hadn't created any domains as such.  I then applied the
YOU update for the kernel and could no longer boot Xen.

The main error during boot is :

kernel BUG at drivers/xen/balloon/balloon.c:463 (dealloc_pte_fin)!

[ I would have given you a serial dump, but the serial port on the machine is dead ]


Billy.

That's ok. Please remember to check the checkbox "This comment provides the
needed information", else it might lose attention. (I've done it for you ;-)
Comment 6 Michael Radziej 2005-09-14 11:34:43 UTC
Etoulas, can you please verify this and then assign back to me?
Comment 7 Michael Radziej 2005-09-14 16:18:41 UTC
Billy, we tried this with rc2 and it worked. There were some problems with xen
in beta4, so I think this has been fixed. Please update to rc2 or later
(currently we have rc4 here) and reopen if the bug persists.

Thanks to etoulas for testing this.
Comment 8 Billy Allan 2005-09-15 07:42:36 UTC
Hi,

I can't find anything newer than RC1 on the download page or mirrors?  Is there
somewhere to download RC2 or later?


Billy.
Comment 9 Andreas Jaeger 2005-09-15 09:44:33 UTC
The goldmaster will be made available early october.

How do I test the solution offered by Michael?  Or am I just to wait for a month
and hope for the best?

Comment 11 Andreas Jaeger 2005-09-15 11:24:31 UTC
Either use RC1 or wait three weeks.

We're planning to make further updates for Xen as well, we might release
something sooner but need further time to test.
Comment 12 Andreas Gruenbacher 2005-09-15 11:37:45 UTC
This really sounds like a kernel problem. 
ftp://ftp.suse.com/pub/projects/kernel/KOTD also has the up-to-date 
(Goldmaster and newer) kernel. Could you please try that? 
Comment 13 Michael Radziej 2005-09-15 12:06:15 UTC
Billy: I wasn't aware that rc2 or later is not available to you, sorry. Then try
rc1 with the kernel from comment #12, that's as close as we can get for now.
Comment 14 Billy Allan 2005-09-15 12:11:44 UTC
Ok - I'm downloading the kernel images now.  I will post an update once they are
in place.
Comment 15 Billy Allan 2005-09-15 15:21:26 UTC
Installed RC1 with a default install + xen + c/developer.  System boots ok. 
Then installed the kotd and rebooted.  On picking the Xen option I get a
fraction of a second of the kernel printing something, then the system reboots.
Picking the regular kernel boots fine.

No other configuration of the system was done.

The system is a Dell Optiplex GX270 if that helps any :

Comment 16 Andreas Gruenbacher 2005-09-15 15:25:19 UTC
Which kotd have you been using (uname -rpv should be enough)? 
Comment 17 Billy Allan 2005-09-15 15:37:07 UTC
2.6.13-20050914161152-default #1 Wed Sep 14 16:11:52 UTC 2005 i686






Comment 18 Michael Radziej 2005-09-19 08:33:47 UTC
It's not a YOU but a xen or kernel bug.
Comment 19 Kurt Garloff 2005-10-06 18:42:52 UTC
Agreed. 
Testing with the final xen (6715) aka kernel-xen-2.6.13-15 would be useful. 
But we'll indeed publish updates soon. 
Comment 20 Kurt Garloff 2005-12-20 20:10:28 UTC
I assume this is fixed.
