What if you kick off 2/3x that many package builds ? Usually it happens after a few hours. I tried kicking the load above 10 by additional running make buildworld -j 10 and the machine froze within a few minutes, without breaking into ddb. Unrelated, i am getting different panic, which does not look ppc-specific: It happens reproducable when i try to compile the nss port (or the one included in mozilla) panic: mutex Giant not owned at /usr/src/sys/kern/kern_mutex.c:299 KDB: enter: panic [thread pid 20485 tid 100084 ] Stopped at 0x251a5c: lwz r11, r1, 0x0 db> where Tracing pid 20485 tid 100084 td 0x15d074b0 0xdd131a10: at panic+0x134 0xdd131ab0: at _mtx_assert+0x74 0xdd131ad0: at _mtx_unlock_flags+0xec 0xdd131b00: at do_execve+0x98c 0xdd131c70: at kern_execve+0xb4 0xdd131ca0: at execve+0x58 0xdd131ce0: at syscall+0x29c .. regards tilman
