I've been enabling more of the laptop-y features as I polish off my upgrade (I'm going from 5.4BETAsomething to 6.0-STABLE, encouraged by losing my hard drive and being handed the clean slate). I *have* started getting occasional hangs after a suspend/resume cycle. It seems to be related to the mouse. I get it with both X and on the console. I've disabled the psm flag that mega-kicks the device (0x300000?) and end up with a dead mouse. Restarting the moused via /etc/rc.d/moused gets my mouse back, but I'll frequently hand immediately afterwards. I've disabled synaptics support and am waiting to see if that makes a difference, other than disabling my middle mouse button.... g. _______________________________________________ freebsd-stable@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-stable To unsubscribe, send any mail to "[EMAIL PROTECTED]"
