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:
