7.0-Release Generic i386, stock kernel, atapci0: SiI 3124 SATA300 PCI-X controller
>Description:

The FreeBSD-7 stock kernel locks 1/4 way thru newfs "writing superblocks" to a three drive GEOM graid3 array when gjournal is active.

>How-To-Repeat:
Simply make a graid3 label, activate a gjournal label, and make a new filesystem with newfs.
>Fix:


>Release-Note:
>Audit-Trail:
>Unformatted:
 >> graid3 label gr0 ad4 ad6 ad8
 >> gjournal label raid3/gr0
 >> newfs -J -O 2 raid3/gr0.journal
 
 It makes no difference if the array is degraded, it still locks up.
 
 Also, when gjournal is not active, newfs is issued and works normally.
