Chris Han (BCC'ed) mailed me to let me know he'd narrowed the
problem down to the 'dio-handle-eof.patch'. Reverting it makes things
work for me too. Yay!

vgchange -a y logs that it 'Failed to read label area' for the
'missing' pv's.
I've put up some possibly useful traces, but I think I've picked out
the relevant bits just below:
http://home.columbus.rr.com/jfannin1/vgchange-trace-good.txt
http://home.columbus.rr.com/jfannin1/vgchange-trace-bad.txt
Some (but not all) partitions opened are reading alternately (the -1024 is
constant):
read(4, 0xbfffe600, 2048) = ? ERESTARTSYS (To be restarted)
read(4, "\300;9\230", 2048) = -1024
If there's anything else that wants investigating, I'm still
willing as my free time allows. Thanks!
