Public bug reported:
Binary package hint: linux-image-2.6.28-11-generic
With Jaunty kernel, the following things have happenned:
- almost always, first attempt at gdm login will take a very long time to go
from user prompt to password prompt
- almost always this first try will not log in, but instead kill gdm and
restart X
- random hangs
- some processes segfault for no good reason (e.g. sudo)
None of this happenned in previous (2.6.27) kernel and booting into it
seems to be a lot better (apart from a warning that cpu ferquency
scaling isn't supported).
