Ok with an updated RELENG_5 and g_mirror.c patched with v 1.34, 1.35
and 1.36 and also with your gmirror.patch, which adds g_waitidlelock()
I still get the setrootbyname failed message and then it goes to the
mountroot> prompt.

I'll try without the gmirror.patch and see how that goes, but it will
be a few hours because syncing takes a while on two 120G disks.

Something that still bothers me are those

GEOM_MIRROR: Cannot update metadata on disk ad0 (error=1).

messages I get with the standard RELENG_5 kernel. Why do it only
happen to ad0 and never to ad2? Is it really a write error or
did the error happen somewhere else inside geom?
