> what were you doing to trigger this ?



It happened after :
- a bunch of updates, including kernel update from 3.2.10 to 3.3.0-4
- first reboot ok, all works fine
- add a friend's disk, to try to fix a boot error on it
- the computer tries to boot, but cycles after grub screen: 5 4 3 2 1,
then 4 lines of text, then reboot, 5 4 3 2 1, 4 lines... see ?
- remove the fiend's disk
- same problem !!!
- then I chose the previous kernel at boot, it works (3.2.10)
- being curious, I try kernel 3.2.9, works ok
- once more 3.2.10 ok
- then "normal" reboot (kernel 3.3), works fine, but with the warning
for this bug...

I hope this is helpful, and I hope you understand my english...

Regards,
Philippe Noroy

do you have anything unusual on your boot command line ? It's curious that you're the only person seeing this.
