So every time I reboot, I get a panic (I believe someone else may be having this problem too). I've included a capture of the ddb session at the bottom. Unfortunately, I can't get a core dump. But, what really sucks, is if I did a 'MAKEDEV all', permissions in /dev get hosed when the machine comes back up. MAKEDEV is doing the right thing, because I've checked to make sure the devices have the correct permissions. When the machine comes back up, things like null, zero, tty, lose their write permissions, which hoses things up. A copy of the kernel can be found on leaf:~pavalos/public/kernel.0713 or at: http://www.theshell.com/~pavalos/crash/kernel.0713 Here's the ddb session (hand-typed): mfree: m->m_nextpkt != NULL Trace beginning at frame 0xde0128bc m_free(c02c7f1f,10,0,d9,de012944) at m_free+0x5e m_free(ddfce000,de012944,da7c4e40,de01297c,de012910) at m_free+0x5e sbdrop(de012944,e9,de012914,c01bd603,de012950) at sbdrop+0x7b sbflush(de012944,de01297c,de012930,c01c5f0d,ddfce000) at sbflush+0x44 sbrelease(de012944,da7c4dc0,c02fd6b4,d9,1000,500,8000,1,ddfce000,0,ddfced00,0,0, 0,da7c4e30,0,40,da7c4e44,0) at sbrelease+0x12 sorflush(da7c4dc0,da7c4dc0,ddea11c0,de0129c8,c01bdf9f) at sorflush+0x10d sofree(da7c4dc0,0,ff80044c,ddea1200,ddea11c0) at sofree+0x92 soclose(da7c4dc0,ddea11c0,de012a20,c017c37a,ddea11c0) at soclose+0x149 soo_close(ddea11c0,d6527300,0,e94d4000,3) at soo_close+0x27 fdrop(ddea11c0,d6527300,de012a64,c0194edb,c02f996c) at fdrop+0xb5 closef(ddea11c0,d6527300,c02f48e0,18,0) at closef+0x17a fdfree(d64fd680,c02f5040,2,c03352e0,100) at fdfree+0x212 exit1(100,de012d40,c02a63ce,de012c24,de012d10) at exit1+0x1ba exit1(de012c24,de012d10,4,c0356b20,1) at exit1 syscall2(2f,2f,2f,f,8050180) at syscall2+0x28a Xint0x80_syscall() at Xint)x80_syscall+0x2a pflog0: promiscuous mode disabled boot() called on cpu#1 Waiting (max 60 seconds) for system thread vnlru to stop...stopped Waiting (max 60 seconds) for system thread bufdaemon to stop...stopped Waiting (max 60 seconds) for system thread syncer to stop...stopped syncing disks... 6 7 7 7 7 7 7 7 7 7 7 7 7 7 7 7 7 7 7 7 giving up on 7 buffers Debugger("Busy buffer problem") CPU1 stopping CPUs: 0x00000001 stopped Stopped at Debugger+0x44: movb $0,in_Debugger.0 db> panic panic: from debugger mp_lock = 00000001; cpuid = 1; lapic.id = 06000000 Trace beginning at frame 0xded829f0 panic(c02c65b1,6000000,c02c2de4,ded82a20,0) at panic+0xd9 panic(c02c2de4,ded82aec,c01394b2,c028e0e7,0) at panic+0xd9 db_command_loop(c028e0e7,0,ffffffff,ded82a50,ded82a4c) at db_command_loop db_command(c03132b0,c02ef5e0,c02ea1d4,c02ea1ec,ded82b20) at db_command+0x2b1 db_command_loop(c028e0e7,c0367d40,c0317880,1,0) at db_command_loop+0x75 db_trap(3,0,1,1,ded82b6c) at db_trap+0xc8 kdb_trap(3,0,ded82b74,0,0) at kdb_trap+0x17b trap(18,10,ded80010,0,c3f35ea0) at trap+0x55e calltrap() at calltrap+0xc --- trap 0x3, eip = 0xc028e0e7, esp = 0xded82bb4, ebp = 0xded82bbc --- Debugger(c02c64bc,7,0,7,7) at Debugger+0x44 boot(0,ded82d40,c02a63ce,ded82c24,ded82d10) at boot+0x2dc reboot(ded82c24,ded82d10,4,deb82500,1) at reboot+0x2c syscall2(2f,2f,2f,0,0) at syscall2+0x28a Xint0x80_syscall() at Xint0x80_syscall+0x2a boot() called on cpu#1 Uptime: 5m46s LWKT_WAIT_IPIQ WARNING! 1 wait 0 (-1) panic: LWKT_WAIT_IPIQ mp_lock = 00000001; cpuid = 1; lapic.id = 06000000 boot() called on cpu#1 Uptime: 5m46s LWKT_WAIT_IPIQ WARNING! 1 wait 0 (-2) panic: LWKT_WAIT_IPIQ mp_lock = 00000001; cpuid = 1; lapic.id = 06000000 boot() called on cpu#1 Uptime: 5m46s LWKT_WAIT_IPIQ WARNING! 1 wait 0 (-3) panic: LWKT_WAIT_IPIQ mp_lock = 00000001; cpuid = 1; lapic.id = 06000000 boot() called on cpu#1 Uptime: 5m46s At this point, I just power-cycled the machine...
