Hi all,
I just compiled the kernel now, the date is:
Sat May 4 14:18:08 BST 2002
I couldn't get a trace as I don't have a serial console or kernel dumps
because of some S_Clockinfo problem. Anyway, the panic message was like
this; just after trying to mount root:
%%
panic: mutex Giant not owned at /data/dev/src/sys/vm/vm_map.c:2151
Debugger:("panic")
=2E..
%%
As far as I am aware, this happens after rev. 1.229 of vm_map.c:
%%
RCS file: /home/ncvs/src/sys/vm/vm_map.c,v
Working file: vm_map.c
head: 1.229
description:
----------------------------
revision 1.229
date: 2002/05/04 02:07:36; author: alc; state: Exp; lines: +0 -3
o Remove GIANT_REQUIRED from vm_map_lookup_entry() and
vm_map_check_protection().
o Call vm_map_check_protection() without Giant held in munmap().
----------------------------
%%
Thanks.
