Re: panic on HEAD
:Ok, so I applied the patch. After about 20 hours, the machine starting
:acting weird. It would still ping, but I could not connect via ssh. So,
:I went to the console. I was able to enter username and password, and
:after that, nothing. After about 5 minutes, I ctrl-alt-esc'd, and panic'd
:the machine. The core and kernel is uploading to leaf: ~/public/*.2

Ok, from your dump it looks like the TCP thread on cpu #1 got stuck

the serializer not waking up waiters.
Keep the first patch in place, and apply this patch in addition.
