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: ------------------------------------------------- root@maka:pts/0 ...sys/MAKA> kgdb /boot/kernel/kernel.debug /usr/dump/vmcore.0 [16:43:54] GNU gdb 6.1.1 [FreeBSD] Copyright 2004 Free Software Foundation, Inc.
