Date: 08 Sep 1998 14:29:07 +0200 From: dag-erli@ifi.uio.no (Dag-Erling Coidan =?iso-8859-1?Q?Sm=F8rgrav?= ) To: current@FreeBSD.ORG Subject: DEVFS panic Message-ID: <xzpd8966b58.fsf@hrotti.ifi.uio.no>
next in thread | raw e-mail | index | archive | help
One of my freshly cvsupped and 'make world'ed -current box will
repeatedly and reliably panic if booted with a DEVFS kernel (SLICE or
no SLICE). The panic occurs right after the memory count (i.e. where a
successful kernel would print "DEVFS: ready for devices"). The details
of the panic are as follows (copied via paper):
Fatal trap 12: page fault while in kernel mode
fault virtual address = 0x14
fault code = supervisor read, page not present
instruction pointer = 0x8:0xf013d2b5
stack pointer = 0x10:0xf01fcf5c
frame pointer = 0x10:0xf01fcf74
code segment = base 0x0, limit 0xfffff, type 0x1b
= DPL 0, pres 1, def32 1, gran 1
processor eflags = resume, IOPL = 0
current process = 0 ()
interrupt mask = net tty bio cam
trap number = 12
Of course, there's no dump, but I can provide a copy of the faulty
kernel (stripped, unfortunately; I forgot to keep an unstripped copy).
The exact same kernel without DEVFS works flawlessly. An older kernel
(August 2nd) with the same configuration works flawlessly with DEVFS
and SLICE.
The faulty kernel was compiled with the following version of DEVFS:
root@fixus-ipv6 /usr/src/sys/miscfs/devfs# ident *
