If this doesn't work I can give you an account on, hm, the box which
freezes uses a UML for its network link so if you flip the time on it
you'd get cut off... and on the other machine
For the "date --set" back 5 sec on the host that
freezes an uml indefinitely
(in kernel/time/timekeeping.c, update_wall_time,)
then download
plug_and_play_clownix_network_03
at http://clownix.net
On my host, it does get stuck, but it may depend also on
host and host kernel, I have:
uml_clow
Give random.c a style workover while I'm changing it.

The random driver would essentially hang if the host's /dev/random
returned -EAGAIN. There was a test of need_resched followed by a
schedule inside the loop, but that didn't help and it's the wrong way
to work anyway.
The right way is to ask for an interrupt when there is input available
from the
Alarm delivery could be noticably late in the !CONFIG_NOHZ case
because lost ticks weren't being taken into account. This is now
treated more carefully, with the time between ticks being calculated
and the appropriate number of ticks delivered to the timekeeping system.

These are the patches that I sent earlier this week which flunked
bisection. They are for 2.6.26 as before.

Is it possible for me to get my hands on a UML which is doing this?

Looks good, thanks.
