I came across this assertion failure while running specweb99.
The OS was s10_50 plus bfu of nightly dated (05/05).
CPU minf mjf xcal intr ithr csw icsw migr smtx srw syscl usr
panic[cpu1]/thread=c4a47800: assertion failed: mp->b_next == NULL && mp->b_prev == NULL, file: ../../common/os/putnext.c, line: 148
The stack trace looks like this:
