Oddly enough it works fine when running. Below is the information i gathered, i dont know what commands to feed the debugger to provide useful info, so instructions are welcome. I have also defined dumpdev in rc.conf and makeoptions DEBUG=-g" in kernel, but the system does not dump. I dont understand why, even dmesg reports its setup. kernel dumps on /dev/ad0s1b swapon: adding /dev/ad0s1b as swap device It just sits there after the panic message. And yes, the swap partition is larger than physical memory. Anyways, here is what i gathered. This happens on a 1 month old kernel, as well as a recently cvsuped one. --- root@fbsd:~# sync root@fbsd:~# /usr/local/etc/rc.d/iplog.sh stop iplogroot@fbsd:~# kernel trap 12 with interrupts disabled Fatal trap 12: page fault while in kernel mode fault virtual address = 0x4 fault code = supervisor read, page not present instruction pointer = 0x8:0xc051274f stack pointer = 0x10:0xd8a55b04 frame pointer = 0x10:0xd8a55b2c code segment = base 0x0, limit 0xfffff, type 0x1b = DPL 0, pres 1, def32 1, gran 1 processor eflags = resume, IOPL = 0 current process = 526 (iplog) [thread pid 526 tid 100105 ] Stopped at propagate_priority+0x13f: movl 0x4(%eax),%eax db> trace Tracing pid 526 tid 100105 td 0xc1b85730 propagate_priority(c1b85730,0,c0649a96,254,c0698620) at propagate_priority+0x13f turnstile_wait(c19a7858,c1b878a0,c0645f57,216,c19a7858) at turnstile_wait+0x38b _mtx_lock_sleep(c19a7858,c1b85730,0,c06495f9,206) at _mtx_lock_sleep+0x134 _mtx_lock_flags(c19a7858,0,c06495f9,206,1) at _mtx_lock_flags+0xbf sleepq_calc_signal_retval(0,0,c0647242,da,0) at sleepq_calc_signal_retval+0x38 msleep(c19ab400,c19ab468,11a,c064fdf9,0) at msleep+0x3de bpfread(c19abd00,d8a55c80,0,3a2,8000) at bpfread+0x1bc devfs_read_f(c1a16a20,d8a55c80,c1551d00,0,c1b85730) at devfs_read_f+0xa6 dofileread(c1b85730,c1a16a20,7,807d000,8000) at dofileread+0x9b read(c1b85730,d8a55d14,c,3ff,3) at read+0x6b syscall(2f,2f,2f,808f600,0) at syscall+0x245 Xint0x80_syscall() at Xint0x80_syscall+0x1f --- syscall (3, FreeBSD ELF32, read), eip = 0x281133cf, esp = 0xbfabde0c, ebp = 0xbfabde28 --- db> continue panic: blockable sleep lock (sleep mutex) process lock @ /usr/src/sys/i386/i386/trap.c:696 KDB: enter: panic [thread pid 526 tid 100105 ] Stopped at kdb_enter+0x30: leave db> trace Tracing pid 526 tid 100105 td 0xc1b85730 kdb_enter(c0646b1d,c06937e0,c064a32c,d8a559f0,100) at kdb_enter+0x30 panic(c064a32c,c0657a46,c06461d5,c065d5e6,2b8) at panic+0xcc witness_checkorder(c19a7858,9,c065d5e6,2b8,0) at witness_checkorder+0xc7 _mtx_lock_flags(c19a7858,0,c065d5e6,2b8,c1b85730) at _mtx_lock_flags+0x8a trap_pfault(d8a55ac4,0,4,1ce,4) at trap_pfault+0xa1 trap(18,10,10,c1b86540,c1b85730) at trap+0x34d calltrap() at calltrap+0x5 --- trap 0xc, eip = 0xc051274f, esp = 0xd8a55b04, ebp = 0xd8a55b2c --- propagate_priority(c1b85730,0,c0649a96,254,c0698620) at propagate_priority+0x13f turnstile_wait(c19a7858,c1b878a0,c0645f57,216,c19a7858) at turnstile_wait+0x38b _mtx_lock_sleep(c19a7858,c1b85730,0,c06495f9,206) at _mtx_lock_sleep+0x134 _mtx_lock_flags(c19a7858,0,c06495f9,206,1) at _mtx_lock_flags+0xbf sleepq_calc_signal_retval(0,0,c0647242,da,0) at sleepq_calc_signal_retval+0x38 msleep(c19ab400,c19ab468,11a,c064fdf9,0) at msleep+0x3de bpfread(c19abd00,d8a55c80,0,3a2,8000) at bpfread+0x1bc devfs_read_f(c1a16a20,d8a55c80,c1551d00,0,c1b85730) at devfs_read_f+0xa6 dofileread(c1b85730,c1a16a20,7,807d000,8000) at dofileread+0x9b read(c1b85730,d8a55d14,c,3ff,3) at read+0x6b syscall(2f,2f,2f,808f600,0) at syscall+0x245 Xint0x80_syscall() at Xint0x80_syscall+0x1f --- syscall (3, FreeBSD ELF32, read), eip = 0x281133cf, esp = 0xbfabde0c, ebp = 0xbfabde28 --- db> continue Uptime: 33m37s --- And here is my kernel config: --- machine i386 cpu I686_CPU ident DP options SCHED_4BSD # 4BSD scheduler options PREEMPTION # Enable kernel thread preemption options INET # InterNETworking options FFS # Berkeley Fast Filesystem options SOFTUPDATES # Enable FFS soft updates support options UFS_DIRHASH # Improve performance on big directories options COMPAT_43 # Compatible with BSD 4.3 [KEEP THIS!] options COMPAT_FREEBSD4 # Compatible with FreeBSD4 options SYSVSHM # SYSV-style shared memory options SYSVMSG # SYSV-style message queues options SYSVSEM # SYSV-style semaphores options _KPOSIX_PRIORITY_SCHEDULING # POSIX P1003_1B real-time extensions options KBD_INSTALL_CDEV # install a CDEV entry in /dev options ADAPTIVE_GIANT # Giant mutex is adaptive. # Bus support.
