Similar to me:
o   i386/7-STABLE server,
o   ia64/8-CURRENT client (which at the time of 7-release was
     therefore running 7-release).
o   I switched from UDP to TCP when TCP became default.

I guess if UDP vs TCP is the problem, then it must be fixed
already because I don't see the misalignment panics. I just
don't know when it was fixed...
