This is coming from pcn(4)'s receive interrupt handler. If my understanding is right, it's checking that the packet coming from the nic did indeed come in a single buffer as it should (i.e. if I'm correct, this being triggered indicates a problem with the emulated nic). You should probably switch to an emulated em(4) which is likely to work better. If you have 'watchdog timeout' problems with em(4) on KVM (due to interrupt routing issues) then try -current, which copes better with some nonstandard bios tables that have been a problem with some versions of KVM. (Before this change in -current, people were using 'disable mpbios' in the kernel config editor to work around the issue).
