Re: LACP: Fatal trap 18: integer divide fault while in kernel mode
Please do open a PR and CC me. As well as the stack trace, post your lagg configuration, and, if you can determine it, the ports' state at the time of the crash. -Alan On Sat, Jan 28, 2017 at 11:21 AM, Slawa Olhovchenkov <s...@zxy.spb.ru> wrote: > I am got panic on recent stable: > > Fatal trap 18: integer divide fault while in kernel mode > cpuid = 3; apic id = 06 > instruction pointer = 0x20:0x81453230 > stack pointer = 0x28:0xfe3e56f46480 > frame pointer = 0x28:0xfe3e56f464a0 > code segment= base 0x0, limit 0xf, type 0x1b > = DPL 0, pres 1, long 1, def32 0, gran 1 > processor eflags= interrupt enabled, resume, IOPL = 0 > current process = 12 (swi4: clock (3)) > trap number = 18 > panic: integer divide fault > cpuid = 3 > KDB: stack backtrace: > db_trace_self_wrapper() at 0x8032b3eb = > db_trace_self_wrapper+0x2b/frame 0xfe3e56f460c0 > vpanic() at 0x804e33a6 = vpanic+0x186/frame 0xfe3e56f46140 > panic() at 0x804e3213 = panic+0x43/frame 0xfe3e56f461a0 > trap_fatal() at 0x807b07c2 = trap_fatal+0x322/frame 0xfe3e56f461f0 > trap() at 0x807b0475 = trap+0x6b5/frame 0xfe3e56f463b0 > calltrap() at 0x807946b1 = calltrap+0x8/frame 0xfe3e56f463b0 > --- trap 0x12, rip = 0x81453230, rsp = 0xfe3e56f46480, rbp = > 0xfe3e56f464a0 --- > lacp_select_tx_port() at 0x81453230 = lacp_select_tx_port+0x70/frame > 0xfe3e56f464a0 > lagg_lacp_start() at 0x814504ae = lagg_lacp_start+0xe/frame > 0xfe3e56f464c0 > lagg_transmit() at 0x8144e73f = lagg_transmit+0xbf/frame > 0xfe3e56f46530 > ether_output() at 0x805f30bc = ether_output+0x71c/frame > 0xfe3e56f465d0 > ip_output() at 0x80629935 = ip_output+0x1585/frame 0xfe3e56f46720 > tcp_output() at 0x806b9e16 = tcp_output+0x1876/frame > 0xfe3e56f468c0 > tcp_timer_rexmt() at 0x806c572f = tcp_timer_rexmt+0x4df/frame > 0xfe3e56f46900 > softclock_call_cc() at 0x804fd1b6 = softclock_call_cc+0x156/frame > 0xfe3e56f469b0 > softclock() at 0x804fd754 = softclock+0x94/frame 0xfe3e56f469e0 > intr_event_execute_handlers() at 0x8049d15f = > intr_event_execute_handlers+0x20f/frame 0xfe3e56f46a20 > ithread_loop() at 0x8049d766 = ithread_loop+0xc6/frame > 0xfe3e56f46a70 > fork_exit() at 0x80499e25 = fork_exit+0x85/frame 0xfe3e56f46ab0 > fork_trampoline() at 0x80794bee = fork_trampoline+0xe/frame > 0xfe3e56f46ab0 > --- trap 0, rip = 0, rsp = 0, rbp = 0 --- > > (kgdb) info line *0x81453230 > Line 848 of "/usr/src/sys/modules/if_lagg/../../net/ieee8023ad_lacp.c" starts > at address 0x8145322e <lacp_select_tx_port+110> and ends at > 0x81453233 <lacp_select_tx_port+115>. > > Do I need to create PR? > ___ > freebsd-...@freebsd.org mailing list > https://lists.freebsd.org/mailman/listinfo/freebsd-net > To unsubscribe, send any mail to "freebsd-net-unsubscr...@freebsd.org" ___ freebsd-stable@freebsd.org mailing list https://lists.freebsd.org/mailman/listinfo/freebsd-stable To unsubscribe, send any mail to "freebsd-stable-unsubscr...@freebsd.org"
