Hi!
After a 12hour upgrade what I can report is that it seems that 2 boots are taking place: Ubuntu 9.04,then Ubuntu 9.10.
Otherwise everything 's working fine!
At grub I notice the new kernel 2.6.31,some lines below there is the 'old' 2.6.28.Everything else is related to to 2.6.31 except for that [x. x.28] one.I would even remove it if I knew how...
An earlier upgrade(I'm running 2 ubuntus on ny HD) from Ubuntu 6.0.6 --> Ubuntu 8.04 showed some overlapping from sda? to USB DISK,corrected by partitioning. Something in common with bug #462355.
Salve Ubuntu!
