(I also have ALSA CVS and lm sensors 2.6.3 installed.) Anyway, I decided to compile in the PNPBIOS feature and discovered that: # cat /proc/bus/pnp/escd is a synonym for "cold reboot". Now I understand that *writing* to random /proc files is a Bad Thing, but reading them??? I would have thought that the worst I could have done would have been corrupting my termininal. Is the escd file my actual ESCD area? Is this a bug, or just a case of "don't do that!"? Cheers, Chris
