Hello,

I just booted the 3.0_BETA kernel from the daily autobuilds and it works!
Thanks a lot for thit work.

I encountered several issues, however:

1/ most serious: Xfree86 crashed with signal 11 when switching desktops in
windowmaker. This never happened with my 2.0_BETA/i386 kernel. The whole
userland is 2.0_BETA, but this shouldn't matter, no? What could be done to
debug this?

2/ some utilities print something like "ksyms: device not configured" when
booting, and vmstat doesn't work. I found the answer in the post
Message-ID: <20050409182722.GA10451@antioche.eu.org>
- it is necessary to use a patched Xen to load the symbol table for domain
0, which one can get by ftp from pub/NetBSD/arch/xen/xen20.
Could this information be added to the Xen HOWTO
(http://www.netbsd.org/Ports/xen/howto.html#netbsd-domain0), please?  For
example: "Until a version of Xen which supports loading the symbol table
is released, it is better to use a patched version available from
ftp://ftp.NetBSD.org/pub/NetBSD/arch/xen/xen20/xen205-loadksym.gz
Otherwise, commands like netstat or vmstat will probably fail and symbolic
kernel debugging in ddb will be impossible."

3/ This is probably harmless, but the SCSI bus scanning is very verbose:
