I'm clutching at straws too, hoping this message is a clue to why
my machine is hanging (i.e. if the NIC is dying, solutions like
init 1/init 3 won't work because the machine is locked up too!).
So, is it something that could be expected to hang the machine?
Brendan
PS I don't know what the NIC is, but the machine's a Dell Optiplex GX110,
RH6.2.
