Comment 56 for bug 601299

12.04b1 on thinkpad x41, update from 11.10 installed on btrfs.

Started at 00:00 AM with all packages for the update downloaded, the reboot and finish occurs on 04:00 PM, thats 16 hours for 4.5gb of data. The laptop is equipped with an solidata ssd that reed and write around 120mb/s. Bootup for the fresh 12.04b1 system is around 6 minutes to login!

Thats simply horrible slow, i will kick btrfs out for now and use xfs instead.
