Modified Files: src/sys/arch/powerpc/powerpc: locore_subr.S Log Message: in cpu_switchto() and the fast-softint context switch code, put back the stwcx. instruction to clear the reservation. we used to have this in the old cpu_switch() until it was if-0'd in 2003 and removed completely in 2007. this fixes hangs I've seen where a softint thread is blocked waiting for a mutex that is not held. this should also fix PR 44387.
