Kernel Panic followed by grub melt down

Hi all,

we have been running opensuse 10, 11, 11.1 on two latitude d630s, very stable and minimal issues.

since upgrading to opensuse 11.2, we have experienced kernel panics on both, after resetting we are getting “error loading operating system” on booting, suspect grub is nuked at some point.

we have tried with ext4 and ext3 and see the same results.

we install the nvidia drivers from their repositories, the bcm43xx wireless drivers from packman and vmware workstation 7.

Where should I start looking for the cause of the kernel panics ?

got to the bottom.

wipe your hard drive before upgrading, both laptops now stable.
