I thought this was the extended interrupt descriptor; sorry my confusion. Meanwhile I changed the dsdt to use the _real_ extended enhanced advanced improved interrupt descriptor, and freebsd now boots. FC6 and Windows survived. I'll push this after further testing. -- Any sufficiently difficult bug is indistinguishable from a feature. ------------------------------------------------------------------------- This SF.net email is sponsored by: Splunk Inc.
