FreeBSD asdf.dk 4.1-RC FreeBSD 4.1-RC #0: Thu Jul 27 10:27:03 CEST 2000     hroi@asdf.dk:/usr/src/sys/compile/ASDF  i386

kernel image, kernel conf file and dmesg output at http://asdf.dk/crash/ (beware asdf.dk is the machine in question)

>Description:
This was caught during an ftp transfer, has happened a couple of times lately:

Someone at the console managed to scribble this down onto paper then email:

processor eflags = interrpt enabled, resume, IOPL=0
current processes = idle
interrupt mask = net tty
trap number = 12
panic: page fault.

syncing disks

fatal trap 12: page fault while in kernel mode.
fault virtual address = 0x30
fault code = supervisor read, page not present
instruction pointer = 0x8:0xc0213ec8
stack pointer = 0x10:0xc02a065c
frame pointer = 0x10:0xc02a0660
code segment = base 0x0, limit 0xfffff, type 0x1b DPL0, pres 1, def321, gran 1
processor eflags = interrupt enabled, resume, IOPL=0
current processes=idle
interrupt mask = net tty bio cam
trap number = 12
panic: page fault

uptime: 1h37m34s
>How-To-Repeat:
Transfer files over ftp (using /usr/libexec/ftpd -D -l -S -4). Not that I think it is directly related to that.

 Whoops, should have been in kern category. Can someone reassign?
