I could solve this on my systems:
I run a patched version of g_mirror.c. The patch was posted for RELENG_5
testing by Pawel and it seems that things work fine w/ his patch. Hopefully
I will report his patch working tonight.
The main reason for the root-mirror breakages on my systems was that gdm uses
the 'reboot' command by default, which makes no use of the swapoff command.
So the swap-devices had been left with the DIRTY flag. When I use the
'shutdown -r' command instead of 'reboot' all mirrors start in ACTIVE state
after rebooting the system.
