I'd just like to mention a long-standing bug (regression) in Ubuntu's kernels
which still persists with the 2.6.12 kernel that shipped with Breezy Preview.

I have an IBM Thinkpad 600 which is currently running Hoary.  When I upgraded
from Warty-->Hoary (fresh install) I started experiencing problems with my USB
mouse and USB camera not working after resuming from a suspend-to-ram.  I have
verified that this a change somewhere in the kernel caused this problem, because
when I install the old 2.6.8 kernel from Warty on top of Hoary, USB works fine
with suspend-to-ram.  It broke possibly with 2.6.9 and surely with 2.6.10.

This bug concerns the 2.6.12 kernel shipped with the Breezy Preview CD. 
Basically, it behaves exactly the same as the 2.6.10 kernel.  I am unable to
give good error messages at the moment because upgrading the libc seems to have
broken all 3 of the terminals I have installed.  I am sure that this is a
regression in the kernel, and not in the APM or hotplug scripts (if there were
any changes) because as I said, Warty's kernel fixes the issue on a fresh Hoary
system, with no changes to any scripts.  I'm not ready to upgrade to a full
Breezy system yet, but I hope this bug report on the Breezy kernel only will be

Please note the old report I made on this for Hoary (also a Preview version):

Also please note a forum posting I made that has some more error messages.

This bug does not exist with any kernels I've tried as new as 2.6.11 coming from

Thanks a lot!
