Package: linux-image-3.0.0-2-sparc64-smp
Version: 3.0.0-6

Hello,
On my Sunfire 280r there is a sil3112 chip based SATA1 dual port controller and there are two 1GB HDD on it in stripe and I use XFS on that stripe.
I use the unstable linux-image kernel because kernel in testing lastly tried kernel crashed at boot (http://old.nabble.com/Kernel-3.0-fails-to-boot-on-V240-td32376229.html) 

On big workload the kernel (seems) randomly crashing:

Hi

This bug was filed for a very old kernel or the bug is old itself
without resolution.

If you can reproduce it with

- the current version in unstable/testing
- the latest kernel from backports

please reopen the bug, see https://www.debian.org/Bugs/server-control
for details.

Regards,
Salvatore
