It means, that the process is waiting for a mutex. There is no information on
what mutex it is waiting on, probably something related to a disk driver.

You can use the 'crash' utility or the DDB kernel debugger to get a
backtrace. This shows where the process is waiting, which is a good
hint on what it is waiting for.

Probably nothing.
