Just to chime in: I get these panics almost daily on my laptop since
the last update (including tcp_input.c 1.198). They used to happen
before as well, but less frequently. Sadly, I no longer seem to get
crashdumps, but back when I did get them, the code path looked the
same (trap somewhere in tcp_input).
The crashes can happen at any time, even under very light load and are
invariably preceeded by the mouse freezing up, then a flurry of
error messages like:
psmintr: delay too long; resetting byte count
psmintr: out of sync (0000 != 0080).
psmintr: discard a byte (1).
psmintr: delay too long; resetting byte count
psmintr: out of sync (0000 != 0080).
psmintr: discard a byte (1).
Then the mouse recovers, but after that it looks like almost any
network activity will trigger a panic. WITNESS does not print
anything.

(Since the d*mn ACPI does not work anyway, I predict a "downgrade" to
4.8 in the near future...)
