That looks likely ok.

So far this behaviour sounds pretty much the same as my Compaq Armada 1500c before adding options SC_NO_SUSPEND_VTYSWITCH to the kernel, or test it with hw.syscons.sc_no_suspend_vtswitch=1 in /etc/sysctl.conf > suspend used to work on this laptop long ago, with a older version of > FreeBSD. Probably 4.4 to 4.8 or so. Mine's on 5.5-STABLE, but I don't think the APM stuff has changed on 6. If using USB, you might want to look into kldunload usb in rc.suspend and corresponding kldload usb in rc.resume, as suggested in those files, if you get that far .. Cheers, Ian
