Bug#536354: linux-2.6: [s390,lenny] kernel panic during boot

Package: linux-2.6
Version: 2.6.26-17
Severity: important

A user reported on d-s390 [1] that a Lenny installation on s390 failed
with a kernel panic during boot. I could reproduce the panic on my
Hercules system using the installer.

I then installed the current Lenny kernel on my installed Hercules system
(running sid), and when I rebooted that with .26 I got the same panic, so
it looks to be a kernel problem and not an installer problem.

We included an s390 specific patch in 2.6.26-16 for #511334, but TBH I
would be surprised if that was the cause given that it was very well
tested.

I'll try to look into this myself but can't give an ETA for results.

Cheers,
FJP

Compared with a successful boot with .26-1 I see no strange differences
in the part of the boot log before the panic.
