Additional information:
Kernel panic - not syncing:VFS:Unable to mount root fs on unknown-block(0,0)
CPU:2 PID: 1 Comm: swapper/0 Not tainted 4.4.5-server-2.mag5 #1
Hardware name /DQ35MP, BIOS JOQ35/OJ.86A.1056.2009.0427.2004

Root file system: btrfs
It is only the i686 server kernel that has this problem.
I have booted 3 x86_64 desktop versions without any problems.

And there is no problem on the same system with an older kernel?

On different systems, I assume?

No problem with older server kernels on this system.
yes, x86_64 on 3 different systems. One uses ext4,
the other 2 use btrfs for / .
Comment 4 Bjarne Thomsen 2016-03-12 20:46:00 CET
But the hardware is different on the 4 systems.
Comment 5 Thomas Backlund 2016-03-12 20:56:01 CET
I dont really see how the 3 security fixes that were the only changes between -1.mga5 and -2.mga5 would do this...

Could there have been some temporary issues during kernel install ?

Have you tried to re-install the kernel. either by removing it and reinstalling it, ro by telling urpmi to reinstall/overwrite it with:
urpmi --media "Core Updates Testing" kernel-server-4.4.5-2.mga5 --replacepkgs
Comment 6 Bjarne Thomsen 2016-03-12 23:07:05 CET
I removed kernel-server-4.4.5-2.mga5
Selected a new media mirror.
Installed kernel-server-4.4.5-2.mga5 again.
Rebooted. It came up without the panic.
I rebooted onece more to be sure.
It came up without a panic.It seems to work.
Yes. Something must have gone wrong during the first install.
Comment 7 Bjarne Thomsen 2016-03-18 07:57:35 CET
Exactly the same panic happened again after an update to kernel-server-4.4.6-1.
I then removed it, and changed the repository to
ftp.acc.umu.se
and installed it again. Now it works.
The first time around I used rpmi --auto-update.

Mass-reassigning all bugs with "kernel" in the summary that are still assigned to tmb (or wrongly assigned to someone with "tmb" in his e-mail address) to the kernel packagers group, but without adding "kernel" to the SRPM field.

Please reassign if needed, or add kernel to the SRPM field if this is correct.

Bug 19460 is a duplicate of this one, but it contains more recent information.

Therefore closing this one and leaving that report open.
