I made some changes to the pmap that could help the situation (rev 1.230 of
arch/alpha/alpha/pmap.c). Can you try updating and see if the problem still
persists? If it happens again, it would be really useful if you could get
a backtrace from all the CPUs. For example:

mach cpu 0
bt
mach cpu 1
bt 
mach cpu 2
bt
....

Thanks,
