I'm afraid I'm still seeing this bug. Or something similar.
I did not get a kernel panic, but my network died and stayed dead. I
was, however, able to reboot.

7222 bytes is likely dictated by my ethernet interface being set for jumbo
frames:
11: eth0: <BROADCAST,MULTICAST,UP,10000> mtu 7200 qdisc pfifo_fast qlen 1000
link/ether 00:1b:fc:1f:33:40 brd ff:ff:ff:ff:ff:ff
this is on the following controller:
03:00.0 Ethernet controller: Realtek Semiconductor Co., Ltd.
RTL8111/8168B PCI Express Gigabit Ethernet controller (rev 01)
I will proceed with some tests of using different NICs to try to isolate
the behaviour.
