Of course, sorry for omitting this. Attached is a diff against the GENERIC kernel. I just recently removed some COMPAT settings, FLOWTABLE and doubled MSGBUF_SIZE to get a complete verbose dmesg dumped (for snd_hda configuration, man that output is huge!). I am currently updating kernel/world and will test a GENERIC afterwards. I'll report back soon Cheers, Ulrich Spörlein --Q68bSM7Ycu6FN28Q Content-Type: text/x-diff; charset=us-ascii Content-Disposition: inline; filename="kernel.diff" --- GENERIC 2009-07-11 20:43:02.147681665 +0200 +++ ELMAR 2009-07-12 10:36:58.000000000 +0200 @@ -1,34 +1,5 @@ -# -# GENERIC -- Generic kernel configuration file for FreeBSD/amd64 -# -# For more information on this file, please read the config(5) manual page, -# and/or the handbook section on Kernel Configuration Files: -# -# http://www.FreeBSD.org/doc/en_US.ISO8859-1/books/handbook/kernelconfig-config.html -# -# The handbook is also available locally in /usr/share/doc/handbook -# if you've installed the doc distribution, otherwise always see the -# FreeBSD World Wide Web server (http://www.FreeBSD.org/) for the -# latest information. -# -# An exhaustive list of options and more detailed explanations of the -# device lines is also present in the ../../conf/NOTES and NOTES files. -# If you are in doubt as to the purpose or necessity of a line, check first -# in NOTES. -# -# $FreeBSD: head/sys/amd64/conf/GENERIC 195618 2009-07-11 15:02:45Z rpaulo $ - cpu HAMMER -ident GENERIC - -# To statically compile in device wiring instead of /boot/device.hints -#hints "GENERIC.hints" # Default places to look for devices. - -# Use the following to compile in values accessible to the kernel -# through getenv() (or kenv(1) in userland).
