>Description:
This machine is a laptop. After a suspend resume cycle
I run dhclient by hand, and sometimes it doesn't work.
Then I hit control C to stop the process and the machine locks
solid and needs to be physically powered off and back on again.
It doesn't always happen, and I cannot reproduce it at will.
But it does happen fairly often.
>How-To-Repeat:
The sequence of events is:
suspend
resume
# killall dhclient
# dhclient em0
machine sits waiting... nothing happens, all other processes
functioning properly.
[control C]
