This seems to be an intermittent problem. I just got my serial console
working again to get you a full stack trace, and the first time I booted the
kernel with your vector domain patch it didn't crash.
Second boot did crash. Here's the stack trace part of the console log:
CPU 9: synchronized ITC with CPU 0 (last diff 0 cycles, maxerr 159 cycles)
CPU 10: synchronized ITC with CPU 0 (last diff 0 cycles, maxerr 40 cycles)
CPU 11: synchronized ITC with CPU 0 (last diff 0 cycles, maxerr 161 cycles)

Kernel panic - not syncing: Aiee, killing interrupt handler!
The bit of ia64_handle_irq where we crashed looks like this:
a000000100011c30: 02 80 00 34 10 10 [MII] ld4 r16=[r26]
a000000100011c36: 00 00 00 02 00 e0 nop.i 0x0;;
a000000100011c3c: 02 c1 7d 53 dep.z r23=r16,7,32
a000000100011c40: 03 00 00 00 01 00 [MII] nop.m 0x0
a000000100011c46: 70 02 40 00 42 c0 mov r39=r16;;
a000000100011c4c: 72 c1 00 80 add r22=r23,r24;;
a000000100011c50: 0d 70 00 2c 18 10 [MFI] ld8 r14=[r22]
r22 has the very bad value of 0xa000008100974780 ... so we die.
