Another quirk some may come across is the udev problem.  Upgrading the 
kernel before upgrading udev is essential.  I expect this will be in the 
release notes eventually.  Many people have upgraded successfully 
without knowing this, probably by upgrading both at once, but it is 
worth knowing.

(The current squeeze udev requires a recent kernel version, version 
2.6.26 is too old; see bug #571255.)
