I use xdm on the laptop; I also run RELENG_6 & RELENG_7 (from other slices), and until the first week of December, I don't recall seeing this before. > You could try disabling drm in your Xorg.conf and > see it that helps. (Option "DRI" "off" in the device section). OK; worth trying. > Do all > of the drm messages appear on the console before it hangs? Yes, but they also appear when it doesn't hang (whether running RELENG_6, RELENG_7, or HEAD). > I'm most suspicious of the acpi errors/warnings, but that isn't > an area that I have experience with. I believe an appropriate technical term is "black art." :-} OK; the laptop has rebooted (following the above-cited change), and for a "sample size" of 1, there was no period longer than about a second or so that the screen stayed dark. So if that's repeatable, I'd suspect something involving DRI/drm, possibly involving interrupt handling...? =20 > robert. Thanks for the suggestion. Peace, david --=20 David H.
