Subject:   ACPI problems with this morning's -CURRENT
Message-ID:  <20030908022345.GB769@sentex.net>

I set up a box yesterday to play with -CURRENT on.  I used the 2003-09-06
snapshot code from ftp://current.freebsd.org/.  Initial setup and boot
worked just fine, but when I did a rebuild/reboot last night, this is what I
saw:

    pmap_mapdev: Couldn't alloc kernel virtual memory

So thinking I missed some kernel options, I pulled a couple of things, did
another cvsup/rebuild/reboot this morning, and got the same thing.  I know
that various people have been having ongoing issues with ACPI, but this is
the first problem I've had with it (I have a couple of other boxen running
5.1-RELEASE and 5-CURRENT).

I was able to fix it (and discover that it was ACPI related) by finding this
post (even though it's two years old):

    <http://www.geocrawler.com/archives/3/147/2001/8/0/6526228/>;

The difference is that I'm seeing the pmap_mapdev error immediately after it
spits out the 'real memory' and 'avail memory' lines.

This is being run on a DFI CD70-SC, 512MB DDR SDRAM, with a Via C3 Nehemiah.
