The following reply was made to PR kern/42020; it has been noted by GNATS.

From: Antti Kantee <>
Subject: PR/42020 CVS commit: src/sys/dev
Date: Tue, 8 Sep 2009 20:57:59 +0000

 Module Name:   src
 Committed By:  pooka
 Date:          Tue Sep  8 20:57:59 UTC 2009
 Modified Files:
        src/sys/dev: rnd.c
 Log Message:
 rnd_wakeup_readers() uses rndpool_mtx for its own consistency
 management, so it cannot be called with the mutex held.  There is
 no consistency requirement to synchronize over the whole add-and-wakeup
 operation, as if data is consumed in the window the mutex is locked,
 wakeups will simply be skipped.
 fix from Juho Salminen in PR kern/42020.
