Could you, please, provide the output from 'acpidump -dt | grep -i cpu | grep -i alias' and your MB model. This may not help to decrease power consumption with lower frequencies, but may be your case is covered by the PR at http://www.freebsd.org/cgi/query-pr.cgi?pr=kern/134192 and after the patch your second processor will be attached properly to the est1. And let me guess, you have kernel message like "device_attach: estX attach returned 6"? > 3.

I don't believe that this will help you, given the messages you're receiving, but you can at least give a shot for SCSI emulation on ATAPI devices. -- Eygene _ ___ _.--. # \`.|\..----...-'` `-._.-'_.-'` # Remember that it is hard / ' ` , __.--' # to read the on-line manual )/' _/ \ `-_, / # while single-stepping the kernel. `-'" `"\_ ,_.-;_.-\_ ', fsc/as # _.-'_./ {_.' ; / # -- FreeBSD Developers handbook {_.-``-' {_/ #
