I'm running RELENG_5 (from Friday, just after ALC's mfc of the IPI deadlock fix). Older dmesg at http://people.freebsd.org/~gallatin/quartet/dmesg Occasionally, it will deadlock. Usually while building something (kernel, world, our product, it seems pretty random). When it is in this state, its unpingable and sometimes (but not always) responds to breaks on the serial port. Enabling debugging options like WITNESS is enough to prevent the deadlock. It locked up this morning after a cvsup and a make depend in my kernel build directory. I've appended some diagnostic info. I'll leave it in this state for a while, in case anybody wants more info. Thanks, Drew [halt sent] KDB: enter: Line break on console [thread 100056] db> tr kdb_enter() at kdb_enter+0x2f siointr1() at siointr1+0x3f6 siointr() at siointr+0x5b intr_execute_handlers() at intr_execute_handlers+0x112 lapic_handle_intr() at lapic_handle_intr+0x21 Xapic_isr1() at Xapic_isr1+0x7d --- interrupt, rip = 0xffffffff8025f184, rsp = 0xffffffffb30c1b40, rbp = 0xffffffffb30c1b70 --- _mtx_lock_sleep() at _mtx_lock_sleep+0x114 softclock() at softclock+0x3c2 ithread_loop() at ithread_loop+0xde fork_exit() at fork_exit+0x8f fork_trampoline() at fork_trampoline+0xe --- trap 0, rip = 0, rsp = 0xffffffffb30c1d00, rbp = 0 --- db> show pcpu cpuid = 3 curthread = 0xffffff00d8a184a0: pid 54 "swi5: clock sio" curpcb = 0xffffffffb30c1d10 fpcurthread = none idlethread = 0xffffff00d8a526f0: pid 11 "idle: cpu3" db> show pcpu 0 cpuid = 0 curthread = 0xffffff00d8a35000: pid 14 "idle: cpu0" curpcb = 0xffffffffb2f9ad10 fpcurthread = none idlethread = 0xffffff00d8a35000: pid 14 "idle: cpu0" db> show pcpu 1 cpuid = 1 curthread = 0xffffff00d8a52b90: pid 13 "idle: cpu1" curpcb = 0xffffffffb2f95d10 fpcurthread = none idlethread = 0xffffff00d8a52b90: pid 13 "idle: cpu1" db> show pcpu 2 cpuid = 2 curthread = 0xffffff00aa4426f0: pid 3328 "cc1" curpcb = 0xffffffffb6096d10 fpcurthread = 0xffffff00aa4426f0: pid 3328 "cc1" idlethread = 0xffffff00d8a52940: pid 12 "idle: cpu2" db> tr 3328 fork_trampoline() at fork_trampoline db> ps pid proc uarea uid ppid pgrp flag stat wmesg wchan cmd 3328 ffffff00a8cfc000 ffffffffb6109000 0 2634 2616 0004002 [CPU 2] cc1 2634 ffffff00a47e12e0 ffffffffb61a0000 0 2633 2616 0004002 [SLPQ wait 0xffffff00a47e12e0][SLP] cc 2633 ffffff006b13a2e0 ffffffffb5e80000 0 2630 2616 0004002 [SLPQ wait 0xffffff006b13a2e0][SLP] sh 2630 ffffff00a9387b80 ffffffffb6194000 0 2628 2616 0004002 [SLPQ wait 0xffffff00a9387b80][SLP] xargs 2628 ffffff006d7135c0 ffffffffb5f49000 0 2622 2616 0004002 [SLPQ wait 0xffffff006d7135c0][SLP] sh 2622 ffffff00d85c52e0 ffffffffb3ac9000 0 2616 2616 0004002 [SLPQ wait 0xffffff00d85c52e0][SLP] make 2616 ffffff00a87aa000 ffffffffb619a000 0 2591 2616 0004002 [SLPQ wait 0xffffff00a87aa000][SLP] make 2591 ffffff006d64a8a0 ffffffffb5f40000 8107 2590 2591 0004002 [SLPQ pause 0xffffff006d64a910][SLP] csh 2590 ffffff0016a27000 ffffffffb5e2f000 8107 2587 2587 0000100 [SLPQ select 0xffffffff805d1550][SLP] sshd 2587 ffffff00a93872e0 ffffffffb6191000 0 466 2587 0000100 [SLPQ sbwait 0xffffff00ab466568][SLP] sshd 528 ffffff00d8a21b80 ffffffffb316a000 0 1 528 0004002 [SLPQ ttyin 0xffffff0000e29c10][SLP] getty 527 ffffff00abed28a0 ffffffffb6017000 0 1 527 0004002 [SLPQ ttyin 0xffffff0000bb1c10][SLP] getty 526 ffffff00abcb35c0 ffffffffb601b000 0 1 526 0004002 [SLPQ ttyin 0xffffff0000bb2010][SLP] getty 525 ffffff00abcb38a0 ffffffffb601c000 0 1 525 0004002 [SLPQ ttyin 0xffffff0000bb2410][SLP] getty 524 ffffff00abeed5c0 ffffffffb5fb7000 0 1 524 0004002 [SLPQ ttyin 0xffffff0000b73810][SLP] getty 523 ffffff00abeed8a0 ffffffffb6012000 0 1 523 0004002 [SLPQ ttyin 0xffffff0000af6010][SLP] getty 522 ffffff00abeedb80 ffffffffb6013000 0 1 522 0004002 [SLPQ ttyin 0xffffff0000b73c10][SLP] getty 521 ffffff00abeed2e0 ffffffffb5fb6000 0 1 521 0004002 [SLPQ ttyin 0xffffff0000b72c10][SLP] getty 520 ffffff00abeed000 ffffffffb5fb5000 0 1 520 0004002 [SLPQ ttyin 0xffffff0000b73010][SLP] getty 489 ffffff00abed2000 ffffffffb6014000 0 1 489 0000000 [SLPQ nanslp 0xffffffff805c4cc0][SLP] cron 476 ffffff00abed25c0 ffffffffb6016000 25 1 476 0000100 [SLPQ pause 0xffffff00abed2630][SLP] sendmail 472 ffffff00abed2b80 ffffffffb6018000 0 1 472 0000100 [SLPQ select 0xffffffff805d1550][SLP] sendmail 466 ffffff00abcb3000 ffffffffb6019000 0 1 466 0000100 [SLPQ select 0xffffffff805d1550][SLP] sshd 452 ffffff00abbd4000 ffffffffb601e000 0 1 452 0000000 [SLPQ select 0xffffffff805d1550][SLP] ntpd 379 ffffff006d64a5c0 ffffffffb5f3f000 0 1 379 0000000 [SLPQ select 0xffffffff805d1550][SLP] amd 350 ffffff006d72e000 ffffffffb5f42000 0 1 350 0000000 [SLPQ select 0xffffffff805d1550][SLP] ypbind 347 ffffff00acb925c0 ffffffffb5fb2000 0 1 347 0000000 [SLPQ select 0xffffffff805d1550][SLP] rpcbind 310 ffffff00d819e000 ffffffffb3a69000 0 1 310 0000000 [SLPQ select 0xffffffff805d1550][SLP] syslogd 290 ffffff006d64a2e0 ffffffffb5ee4000 0 1 290 0000000 [SLPQ select 0xffffffff805d1550][SLP] devd 260 ffffff006d72e5c0 ffffffffb5f44000 0 1 260 0000000 [SLPQ select 0xffffffff805d1550][SLP] dhclient 207 ffffff00d85c5000 ffffffffb3ac8000 0 1 207 0000000 [SLPQ pause 0xffffff00d85c5070][SLP] adjkerntz 77 ffffff00d85c5b80 ffffffffb3acc000 0 0 0 0000204 [SLPQ -
