Hi guys,
I am not sure if this is acpi related or due to other issues.
running latest FreeBSD (built yesterday from fresh sources :
FreeBSD ayiin.xxx.com.au 7.0-PRERELEASE FreeBSD 7.0-PRERELEASE #14: Wed Jan 16 01:38:57 EST 2008 root@ayiin.xxx.com.au:/usr/obj/usr/src/sys/AYIIN i386
Hardware is Thinkpad z60m , 1.5 GB of RAM. dmesg (non verbose) is @ end of this mail
I had :

13 1 0xc4b22000 d000 ipfw.ko
14 1 0xccd23000 2000 rtc.ko
PLUS acpi_video.ko loaded in /boot/loader.conf.local.
doing a kldunload acpi_video would panic the kernel. Also happened in single user.
I have crash dumps, but unfortunately, i wiped the kernel.debug after starting a full clean rebuild of kernel + world for today's changes.
I don't know whether this problem happened before 7 - i only started loading acpi_video for a few weeks when I realised I couldn't change the brightness on the screen anymore when under X (works ok in a vconsole)
Anyway, I followed the steps in the handbook to get some info about the crash. I've included 2 crashes here, both caused with kldunload acpi_video:
