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

Hardware is Thinkpad z60m , 1.5 GB of RAM. dmesg (non verbose) is @ end of this
mail
I had :

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:

I rebuilt the kernel (but not world yet) with latest src : FreeBSD ayiin.xxx.com.au 7.0-PRERELEASE FreeBSD 7.0-PRERELEASE #15: Wed Jan 16 10:28:53 EST 2008 root@ayiin.xxxx.com.au:/usr/obj/usr/src/sys/AYIIN i386 i rebooted into single user mode. Loaded acpi_video (I took it out of my loader.conf.local), I removed it and Boom!, panic.

Then grab www.freebsd.org/~jhb/gdb/gdb6 and source it while running kgdb. You can use the 'kldload' command to generate output that you can pass to asf(8) to generate a file you can source to import the symbols into kgdb for the kernel module. Then you can get a stack trace which will help track down the problem. -- John Baldwin
