I'm having a problem with this commit. My ThinkPad 600X panics on boot with this change. If I back it out, all gets back to normal. What information do you need except from a verbose boot log to track it down? (I can grab a text from serial console, etc.) Cheers, -- Ruslan Ermilov [EMAIL PROTECTED] FreeBSD committer
