Hi! I have machine running OpenBSD without any problems. When I put FreeBSD 6.0-R to this machine it started randomly freezing with and without load. It does not respond to keyboard ctrl-alt-esc, ctrl-alt-del (with KDB in kernel) and by network. So I rebuild kernel with DDB, attached serial console, and send break with minicom when it freezed. KD@: enter: Line break on console [thread pid 22 tid 100011 ] Stopped at kdb_enter+0x2b: nop db> where Tracing pid 22 tid 100011 td 0xc0d91300 kdb_enter(c064968f) at kdb_enter+0x2b siointr1(c0e4f800) at siointr1+0xce siointr(c0e4f800) at siointr+0x38 intr_execute_handlers(c067c140,c5a38c7c,c9f38068,c0e33400,6) at intr_execute_ha5 atpic_handle_intr(4) at atpic_handle_intr+0x96 Xatpic_intr4() at Xatpic_intr4+0x20 --- interrupt, eip = 0xc0484d03, esp = 0xc5a38cc0, ebp = 0xc5a38cd4 --- lnc_tint(c0e33400) at lnc_tint+0x47 lncintr(c0e33400) at lncintr+0xf7 ithread_loop(c0d89680,c5a38d38) at ithread_loop+0x159 fork_exit(c04dd348,c0d89680,c5a38d38) at fork_exit+0x70 fork_trampoline() at fork_trampoline+0x8 --- trap 0x1, eip = 0, esp = 0xc5a38d6c, ebp = 0 --- db> show lockedvnods Locked vnodes db> ps pid proc uid ppid pgrp flag stat wmesg wchan cmd 695 c104fc48 0 692 695 0004002 [SLPQ ttyin 0xc0e4fc10][SLP] bash 692 c0ec5418 10641 691 692 0004002 [SLPQ wait 0xc0ec5418][SLP] bash 691 c104f20c 0 1 691 0004102 [SLPQ wait 0xc104f20c][SLP] login 475 c0f84c48 100 435 475 0004000 [SLPQ piperd 0xc0ef2330][SLP] unlinkd 474 c0f8420c 0 1 1 0004000 [SLPQ nanslp 0xc068752c][SLP] getty 472 c0f84418 0 1 472 0004002 [SLPQ ttyin 0xc0e57010][SLP][SWAP] getty 471 c0f84000 0 1 471 0004002 [SLPQ ttyin 0xc0e56010][SLP][QWAP] getty 470 c0f84624 0 1 470 0004002 [SLPQ ttyin 0xc0e55c10][SLP][SWAP] getty 435 c0ec6624 100 433 433 0004000 [SLPQ select 0xc068bf64][SLP] squid 433 c0ec620c 100 1 433 0000000 [SLPQ wait 0xc0ec620c][SLP][SWAP] squid 432 c0ec6c48 1100 418 432 0004002 [SLPQ select 0xc068bf64][SLP] mlnet-real 418 c0ec6830 0 1 43 0004102 [SLPQ wait 0xc0ec6830][SLP][SWAP] su 398 c0e13830 0 1 398 0000000 [SLPQ nanslp 0xc068752c][SLP] cron 385 c0e13624 0 1 385 0000100 [SLPQ select 0xc068bf64][SLP] sshd 242 c0e13a3c 0 1 242 0000000 [SLPQ select 0xc068bf64][SLP][SWAP] devd 151 c0ec520c 0 1 151 0000000 [SLPQ pause 0xc0ec5240][SLP][SWAP] adjkz 42 c0ec5830 0 0 0 0000204 [SLPQ - 0xc5e85d08][SLP] schedcpu 41 c0ec5a3c 0 0 0 0000204 [SLPQ syncer 0xc068729c][SLP] syncer 40 c0ec5c48 0 0 0 0000204 [SLPQ vlruwt 0xc0ec5c48][SLP] vnlru 39 c0ec6000 0 0 0 0000204 [SLPQ psleep 0xc068c4ac][SLP] bufdaemon 38 c0db4c48 0 0 0 000020c [SLPQ pgzero 0xc068fc24][SLP] pagezero 37 c0e12000 0 0 0 0000204 [SLPQ psleep 0xc068f774][SLP] vmdaemon 36 c0e1220c 0 0 0 0000204 [SLPQ psleep 0xc068f730][SLP] pagedaemon 35 c0e12418 0 0 0 0000204 [IWAIT] swi0: sio 34 c0e12624 0 0 0 0000204 [SLPQ - 0xc0d8203c][SLP] fdc0 9 c0e12830 0 0 0 0000204 [SLPQ - 0xc0e20400][SLP] thread taskq 33 c0e12a3c 0 0 0 0000204 [IWAIT] swi6:+ 32 c0e12c48 0 0 0 0000204 [IWAIT] swi6: task queue 8 c0e13000 0 0 0 0000204 [SLPQ - 0xc0d8a480][SLP] acpi_task2 7 c0e1320c 0 0 0 0000204 [SLPQ - 0xc0d8a480][SLP] acpi_task1 6 c0e13418 0 0 0 0000204 [SLPQ - 0xc0d8a480][SLP] acpi_task0 5 c0da5624 0 0 0 0000204 [SLPQ - 0xc0d8a580][SLP] kqueue taskq 31 c0da5830 0 0 0 0000204 [IWAIT] swi5:+ 30 c0da5a3c 0 0 0 0000204 [SLPQ - 0xc0683fe0][SLP] yarrow 4 c0da5c48 0 0 0 0000204 [SLPQ - 0xc0684a48][SLP] g_down 3 c0db4000 0 0 0 0000204 [SLPQ - 0xc0684a44][SLP] g_up 2 c0db420c 0 0 0 0000204 [SLPQ - 0xc0684a3c][SLP] g_event 28 c0db4624 0 0 0 0000204 [IWAIT] swi3: vmt 27 c0db4830 0 0 0 000020c [RUNQ] swi4: clock sio 25 c0d9020c 0 0 0 0000204 [IWAIT] irq14: ata0 24 c0d90418 0 0 0 0000204 [IWAIT] irq13: 23 c0d90624 0 0 0 0000204 [IWAIT] irq12: 22 c0d90830 0 0 0 0000204 [APU 0] irq11: lnc0 21 c0d90a3c 0 0 0 0000204 [IWAIT] irq10: 20 c0d90c48 0 0 0 0000204 [IWAIT] irq9: acpi0 19 c0da5000 0 0 0 0000204 [IWAIT] irq8: rtc 18 c0da520c 0 0 0 0000204 [IWAIT] irq7: ppc0 17 c0da5418 0 0 0 0000204 [IWAIT] irq6: fdc0 16 c0d8b000 0 0 0 0000204 [IWAIT] irq5: 15 c0d8b20c 0 0 0 0000204 [IWAIT] irq4: sio0 14 c0d8b418 0 0 0 0000204 [IWAIT] irq3: 13 c0d8b624 0 0 0 0000204 [IWAIT] irq1: atkbd0 12 c0d8b830 0 0 0 0000204 [IWAIT] irq0: clk 11 c0d8ba3c 0 0 0 000020c [Aan run] idle 1 c0d8bc48 0 0 1 0004200 [SLPQ wait 0xc0d8bc48][SLP] init 10 c0d90000 0 0 0 0000204 [SLPQ ktrace 0xc0685498][SLP] ktrace 0 c0684b40 0 0 0 0000200 [IWAIT] swapper dmesg -a can be found at http://www.dp.uz.gov.ua/dmesg.squid kernel config at http://www.dp.uz.gov.ua/kernel.squid pciconf -lv at http://www.dp.uz.gov.ua/pciconf.squid What addidional information can I provide? -- Best regards, Palij Oleg, ISC (Pridn railway) xmpp://malik@jabber.te.ua
