This is atypical even on a loaded freeBSD dydtem, so I usually notice right away. when that happens, I notice my drive light is on so it must be working on seomthing furiously, but I see nothing too wierd in top/iostat/fuser (though I'm not expert with i/o stat or fuser). A few minutes later my system reboots itself. this is all I get: Fatal trap 12: page fault while in kernel mode fault virtual address = 0x4 fault code = supervisor read, page not present instruction pointer = 0x8:0xc0282f9a stack pointer = 0x10:0xd1f16d28 frame pointer = 0x10:0xd1f16d30 code segment = base 0x0, limit 0xfffff, type 0x1b = DPL 0, pres 1, def32 1, gran 1 processor eflags = interrupt enabled, resume, IOPL = 0 current process = 10791 (usb) interrupt mask = none trap number = 12 panic: page fault syncing disks... 68 9 3 2 1 done Uptime: 3d22h46m22s >How-To-Repeat: Not sure what triggers this, but I think it is USB related. Most recently it happened when I was plugging and unplugging a UBS 2.0 hub with some stuff attached (mouse and printer). Something simmilar used to happen when I used a USB-to-IDE converter, but I didn't manage to get the console output because I wasn't setup with console to seriel port at that time and don't use that device on that machine anymore.
