Public bug reported:

In a lab of 65 computers(8.04 Hardy) some of the computers started to hang 
during boot process.
This happened after a system upgrade of about 100 packages. Kernel version is 
2.6.24-24-generic

First, it stopped after xserver-xorg-input-wacom service was started. I
removed that service from boot process. Then it stuck after syslogd
printed "OK". I tried removing klogd from the boot process but it didn't
help.

When stuck, switching to other virtual consoles does not work. pressing
ctrl+alt+del does not reboot the machine.

When I press alt+sysyrq+e to send TERM, "rc2" process gets killed along
with gettys (and ctrl-alt-del process if I have pressed.) after that,
gettys respawn an I can login from the console. Stopping and starting
syslogd and klogd services works fine. dmesg shows no module errors. And
syslog shows no errors.

While the machine is hanging alt+sysrq+t shows only "events" as the
running process. And some functions about sending udp datagrams can bee
seen from the call stack.

I was not able to pinpoint the problem, any pointers will be
appreciated.
