 A likely fix for this has been applied to current in the following changes:
 
 cvs rdiff -r1.30 -r1.31 src/sys/dev/raidframe/rf_reconmap.c
 cvs rdiff -r1.10 -r1.11 src/sys/dev/raidframe/rf_reconmap.h
 cvs rdiff -r1.103 -r1.104 src/sys/dev/raidframe/rf_reconstruct.c
 cvs rdiff -r1.23 -r1.24 src/sys/dev/raidframe/rf_reconstruct.h
 cvs rdiff -r1.24 -r1.25 src/sys/dev/raidframe/rf_revent.c
 
 Pullups for netbsd-3 and netbsd-4 have been requested.  (I forgot 
 there was an open PR on this, and neglected to put the PR number
 in the commit message..)
 
 Later...
