Hiya guys,
I'm getting the msg "hangcheck: hangcheck value past margin!" every few
minutes in the logs. It started all of a sudden. The kernel is a vanilla
2.6.14.5 on a remote box.
What could this mean ?
Thanks

it means you enabled the hangcheck timer watchdog, and it seems to think
the kernel is too busy or losing time ;)
Did you mean to enable that watchdog?
