According to your motherboard, you have no devices connected to wcd1. If nothing uses the interrupt, wcd1 will _not_ probe. Regardless of enabled or not. techs@obfuscation.org wrote: > > *sigh* > > 250+ questions about wdc1 probing incorrectly from 2.1.0 through > 3.0-RELEASE on -questions, -bugs, and -hardware, and still I haven't seen > an *answer*.

Err.. Am I to assume that Linux has a hdb device if a primary slave exists? If so, the PIIX3 has gotten weirder. -- Kris Kirby UAH Mail <kirbyk@email.uah.edu> UAH CS <kkirby@cs.uah.edu> Home <kris@airnet.net> WWW <nomurphy@hotmail.com> ------------------------------------------- TGIFreeBSD...
