I the test machine that I used to isolate kern/19603, I never see this bug ... all but one of it's ports are not connected. It appears that lots of internet traffic is required to exercise this bug. This bug also doesn't happen with 16 dc ports. The production machine that produced the crash dump does not exhibit the crash with 16 ports. panic: malloc: wrong bucket syncing disks... 2 2 2 2 2 2 2 2 2 2 2 2 2 2 2 2 2 2 2 2 giving up on 2 buffers Uptime: 1d21h24m9s dumping to dev #da/0x20001, offset 1048576 [...] (kgdb) bt #0 boot (howto=256) at ../../kern/kern_shutdown.c:302 #1 0xc015a900 in poweroff_wait (junk=0xc026e2af, howto=0) at ../../kern/kern_shutdown.c:552 #2 0xc022fcd9 in trap_fatal (frame=0xc027835c, eva=99) at ../../i386/i386/trap.c:927 #3 0xc022f9b1 in trap_pfault (frame=0xc027835c, usermode=0, eva=99) at ../../i386/i386/trap.c:820 #4 0xc022f5af in trap (frame={tf_fs = 16, tf_es = -1071448048, tf_ds = -1071448048, tf_edi = 1074174976, tf_esi = -1045939008, tf_ebp = -1071152204, tf_isp = -1071152248, tf_ebx = -1045939008, tf_edx = 1074240664, tf_ecx = 0, tf_eax = 99, tf_trapno = 12, tf_err = 0, tf_eip = 99, tf_cs = 8, tf_eflags = 66054, tf_esp = -1072219758, tf_ss = 1768318561}) at ../../i386/i386/trap.c:426 #5 0x63 in ??
