Upgrade from Sarge to Etch didn't upgrade the kernel and broke software RAID

["Siju George" <sgeorge.ml@gmail.com>]

Hi,

I upgraded from Sarge to Etch one of my servers.
But the kernel is still the old kernel with sarge in the end and not Etch's.
Any idea why?

Also it broke the the Software RAID and made superblocks of some
partition corrupted and I had to use xfs_repair to repair them but
stimm could not mount them as RAID partitions ( md*) only individual
partitions (hda* )

Any Idea why?

Is upgrade painful always like this?

Thanks
