One cause of such panics has recently been fixed (july 7th), so make sure
that you try kernels more recent than that date. However, that particular
bug should not show up so easily..
If the problems are still there even if you are using a post-july 7 kernel,
perhaps you could mail some more info about your system, like disk
geometry, what the disklabel says, does the disk work fine under other
