Thanks, I'm now running a hacked up kernel that's Torvalds' tree from Saturday morning (same as before) + a patch from Benjamin to fix the touchpad + the DSDT hack given above.

Also, suspend/resume now works properly with this new cocktail. --Jason -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
