Hello,
I purchased a Lenovo Thinkpad R500 8716WR8 a few weeks ago. FreeBSd is
running fine on it with one litte problem. Every now and than the system
crashes while suspending. Today I was able to get a crash dump and
extract a backtrace and some more informations.
The hardware:
-------------
Intel Core2Duo T6670 @ 2,2GHz
2048 MB RAM
Intel X4500 Graphic Adapter
Latest available BIOS
The Software:
-------------
% uname -a
FreeBSD maka.home.yamagi.org 8.1-RC2 FreeBSD 8.1-RC2 #0: Wed Jun 30
19:16:52 CEST 2010 root@maka.home.yamagi.org:/usr/obj/usr/src/sys/MAKA
amd64
% sysctl kern.timecounter.hardware
kern.timecounter.hardware: i8254
The crash:
----------
In most cases the systems suspends and resumes just fine. But in about 1
out of 10 times it crashes while suspend. As of today three of this
crashes occured, all of them were the second or third suspend since the
last reboot. And in all cases the system uptime was over 3 hours, I was
not able to provoke this crash right after boot. In all cases the system
was running xorg-server 1.7.5,1 and xf86-video-intel 2.7.1_3. The
console is running in VESA mode with a resolution of 1680x1050:
allscreens_flags="MODE_366"
And now the crash information extracted via kgdb:

Previous frame inner to this frame (corrupt stack?)
Since I have the core dump I can provide more information if necessary.
I could even upload the core and the kernel to web if it helps.
Thanks for your help,
