I've been having problems with vinum volumes since an upgrade from 4.9
to 4.10 which I posted about here:
However maybe that is the *symptom* instead of the *problem*. I shut
down my system from the console and saw this output:
--- BEGIN ---
boot() called on cpu#0
Waiting (max 60 seconds) for system process `vnlru' to stop...stopped
Waiting (max 60 seconds) for system process `bufdaemon' to stop...stopped
Waiting (max 60 seconds) for system process `syncer' to stop...stopped

The operating system has halted.
Please press any key to reboot.

da2 and da3 are two IDE drives in a firewire enclosure. These are also
the drives that come up "referenced" after restarting. What do these
errors mean? How can I correct them? Is the following section from the
sbp man page applicable to my situation?
Some (broken) HDDs don't work well with tagged queuing. If you have prob-
lems with such drives, try ``camcontrol [device id] tags -N 1'' to dis-
able tagged queuing.
Thanks for your help!
