Have you checked /var/log/daemon.log? Maybe it is busy rebuilding/checking corrupt tables, might take a while if it crashed recently.

You could also try top, to see whether the mysql processes are not going zombie or being stalled waiting for I/O (Symbol D, in stead of S), in which case you might have a harddisk problem.
