Hello...

On -current updated May, 30th, at 00.00 I got the following
panic:

panic: softdep_fsync: pending ops

The system was freshly rebooted and I tried to use mutt. At the
moment of the sending of an email, the panic occured.

Here is a trace from the dump:

Anything else, that I need to report?
