I have exact the same problem. I upgrade my ubuntu 11.04 to 11.10 yesterday.
Now I can only boot my Acer Extensa 2902LMi with the grub option acpi=off.
_
The same problem I had had as I installed ubuntu 11.04 a few months ago.
See this bug report:
GREAT! Latest kernel (2.6.38.10) solved this problem for me, too!

Upgraded server from 8.04 LTS to 10.04 LTS on 8/21/2010. Server was
running LTSP with 8.04. Same issue with clients not able to access tftp
directory. The fix suggested by Inno to change the directory and add
--secure worked (THANK YOU!):
# /etc/default/tftpd-hpa
TFTP_USERNAME=tftp
