I have an IPC that periodially netboots an old -current, and I got the
following panic the other day while trying to boot it. The next
attempt worked fine. Is this something worth trying to debug?
Something that's likely already fixed? 

panic: me_alloc: all pmegs gone
data fault: pc=c5d69808 addr=c5d69808 ser=80<INVAL>
panic: kernel fault
