>Environment:
Two RELENG_6 machines, checked out and build yesterday
>Description:
I had several panics with a ggate/gmirror device and am now looking into the problem.
One thing that's clearly wrong, is ggated spitting out socket errors and bad file 
descriptors.

>How-To-Repeat:
Simply export some device with a suitable gg.exports. Run ggated -v, run
'ggatec create host device' on some suitable host. As soon as you run ggatec, ggated
will continually spit out errors like this:

>Fix:

Someone [1] figured out that backing out sys/kern/uipc_socket2.c
rev. 1.147.2.7 fixes the problem (I haven't tried that yet ...)
