I also did the upgrade and everythign went fine.
AH no, you are right, as i was connected to power supply and i let the keyboard open when it did reboot, i got it doing a boot loop.

But once cable removed, keyboard closed and start it properly, everythign went fine.

And i can get my mail from gmail!!! I didn't care enough (or was i lazy? ) to solve it myself using the deb provided in CSSU test thread.

Thks a lot freemangordon to port CSSU test in thumb.
