Comment 36 for bug 569680

Solved!
lspci didn't give me information about controller... so i installed gparted to check better my partion table. gpparted starts and get some time to detecting the device... then i saw and remembered that i have two swaps, but one of them is a swapoff (and it was /dev/sda1 where i get the error message while booting) so i deleted it, and gparted detected again the device but this time very fast... so i reboot the system and in about 15seconds i am logged in kubuntu Maverick 10.10 :-P

If it can help i am using kernel version: 2.6.36-020636-generic

So my problem was a swap partition, i deleted it and everything is ok now :-)
Good luck
