Tracked it down. (sorry for linewraps)

+#define DEV_NEED_TIMERIRQ 0x0001 /* set the timer irq flag in the irq mask */
+#define DEV_NEED_LINKTIMER 0x0002 /* poll link settings. Relies on the timer
irq */
+#define DEV_HAS_LARGEDESC 0x0003 /* device supports jumbo frames and needs
packet format 2 */

My hardware is NEED_TIMERIRQ|NEED_LINKTIMER, however, by this logic, it'll
also be DEV_HAVE_LARGEDESC, which isn't true.

So, you want this instead:

#define DEV_HAS_LARGEDESC 0x0004

After making that change, all is working fine, but then again, I've never run
into the hangs you are debugging. I'll follow up in a couple of days time to
confirm I'm not getting any problems with the new code.
