FreeBSD 6.0, ThinkPad 600, dc0: watchdog timeout - ACPI?

[Fred Koschara]

Hello John --

I captured the dmesg output for
         ACPI, no boot fix
         no ACPI, no boot fix
         ACPI, boot fixed
         no ACPI, boot fixed

The files are at http://fkeinternet.com/support/ where you will find a link 
to 20060607.London.FKEinternet.com.ThinkPad600.dmesg.files.tar.gz which 
contains the debugging information.  In each case, I also included the 
corresponding loader.conf file, similarly named so it will be obvious which 
one is which.

FYI, my immediate problem was relieved by information I received from Björn 
König on the freebsd-questions mail list.  He wrote:

Even though I am now able to get my ThinkPad to boot FreeBSD 6.1 (I 
upgraded after solving the boot issue), I am posting this information in 
the hopes that the contribution will help support FreeBSD on a wider range 
of hardware.  I think FreeBSD is an excellent operating system, and will do 
what I can, when I can, to further its development.

The "war on terror" is a sham:  There is no real protection against 
suicidal maniacs spurred on by creative madmen.  In the end, the only 
outcomes will be the destruction of the American economy due to pouring a 
bankrupting stream of wealth into a bottomless pit, and the final 
destruction of personal liberty in the name of "security."  (When was the
