I'm using a new HP 6715b notebook. When trying to use this with a docking station (PA286), the machine keeps hanging at message "starting default moused:". The machine then just has died (I even can't break into debugger using ctrl+alt+esc). On investigation I figured out, `vidcontrol -m on' (called by /etc/rc.d/moused) is causing that freeze. Using an USB mouse, the system dies immediately when plugging in the mouse ("starting ums0 moused:" appears). Everything is fine when the system is undocked or moused _completely_ disabled. Running with WITNESS enabled does not give anything. Would INVARIANTS give me something here? FreeBSD cesar.sz.vwsoft.com 7.0-PRERELEASE FreeBSD 7.0-PRERELEASE #8: Tue Jan 22 01:29:52 CET 2008 root@cesar.sz.vwsoft.com:/usr/obj/usr/src/sys/CESAR i386 For now, I've commented out the vidcontrol call in /etc/rc.d/moused to work around that issue. Looking at the code in vidcontrol.c, I have no idea what might cause that as it's really simple code and basically just calling an IOCTL. The notebook has got an internal LCD with 1680x1050 and the docking station has a 1280x1024 display connected (what may get some code being confused?). What's going on there? Thx! Volker
