On the 6120, you need to do setpci -s 1f.0 bb.b=84 after every lid event in order to get any more. I /think/ this is a bug with the HP BIOS (the 6220 doesn't do this) - I'm in touch with HP over it now. As for the high kacpid load, I'm only able to trigger this after a suspend to disk, and using the platform option (to ensure the _WAK methods are called) /seems/ to avoid it. Could you try building a kernel with acpi debug support, set the output level fairly high (echo -n 0x0000ffff >/proc/acpi/debug_level) and see what sort of output you get? Warning - there'll be huge amounts of it. Really huge amounts. The stuff we're interested in is whatever appears after kacpid has begun taking up all the processor time. -- Matthew Garrett | mjg59-1xO5oi07KQx4cg9Nei1l7Q@public.gmane.org ------------------------------------------------------- SF email is sponsored by - The IT Product Guide Read honest & candid reviews on hundreds of IT Products from real users.
