I've discovered what may be the same bug on another system -- feebas, a Cisco UCS C220 M4 (Intel Series v3), with the same CPU type (Intel Xeon E5-2640 v3). I'm attaching dmesg output from it, but on this particular run, the computer did not hang indefinitely, although it did become unresponsive for a few seconds.
