I reproduced it on another SMP machine with 6.0 dated from a few days
ago:

panic: vm_fault: fault on nofault entry, addr: deae2000
cpuid = 2
KDB: enter: panic
[thread pid 23563 tid 100231 ]
Stopped atK      kdb_enter+0x32: leave
_sich(1,,c06312e0 ti_sith+0x0
rk_mpoline)t fork_tramone0x1, ei = 0, ep = xa0fd7, bp  0- -db>

Which did at least manage to display the entire panic string and enter
DDB, but then it locked up.
