Hello, hope you're having a nice day, I've been testing my system mostly to check if ZFS in -current is stable, however so far I've been getting kernel panics in every other area except ZFS. This time it's tcp_sack.c according to the panic message, inside [intr]. fujibayashi@ameagari ~ % uname -a FreeBSD ameagari.fujibayashi.jp 8.0-CURRENT FreeBSD 8.0-CURRENT #1 r194546: Thu Jun 25 19:44:18 JST 2009 root@ameagari.fujibayashi.jp:/usr/src/sys/amd64/compile/Ameagari amd64 panic: tcp_sack_globalholes >= 0 cpuid = 0 KDB: enter: panic [thread pid 12 tid 100005] Stopped at kdb_enter+0x3d: movq $0,0x682580(%rip) db> bt Tracing pid 12 tid 100005 td 0xffffff0001320000 kdb_enter() at kdb_enter+0x3d panic() at panic+0x17b tcp_sackhole_remove() at tcp_sackhole_remove+0xc7 tcp_free_sackholes() at tcp_free_sackholes+0x48 tcp_timer_rexmt() at tcp_timer_rexmt+0xb3 softclock() at softclock+0x291 intr_event_execute_handlers() at intr_event_execute_handlers+0x68 ithread_loop() at ithread_loop+0xb2 fork_exit() at fork_exit+0x12a fork_trampoline() at fork_trampoline+0xe --- trap 0, rip = 0, rsp = 0xffffff8000026d40, rbp = 0 --- db > No core saved - when I tried to get it to save the core, it just raised fatal trap 12 (page fault) and got a general protection fault afterwards.
