Architecture: x86_64
Machine: amd64
>Description:
Recent kernel ignores root device parameter specified in
boot loader and always boots from hdXa.
I installed NetBSD/amd64 on wd0a and NetBSD/i386 on wd0f.
(This pc has one disk, so hd0 is wd0.)
They are in same MBR partition. I don't use any dkwedges.
/boot.cfg on wd0a has following lines:
menu=nbamd64 (hd0a):dev hd0a:;rndseed /var/db/entropy-file;boot
menu=nbi386 (hd0f):dev hd0f:;rndseed /var/db/entropy-file;boot
default=1
When I choose second line to boot i386, the boot loader loads
the kenrel from wd0f:/netbsd but the kernel sets the root to wd0a
because it tries to read 64-bit version of /sbin/init from wd0a
and complain about it (ENOEXEC), finally stops with error.

Does this patch help?
change 1:
Use the sizeof() the right thing to compute the length of the
btinfo_userconfcommands. This prevents an anonymous (4-bytes long,
only long enough for the 'len' member) bootinfo_common from being sent
to the kernel.
change 2:
Don't track in add_biosdisk_bootinfo() whether the BTINFO_BOOTWEDGE and
BTINFO_BOOTDISK bootinfo has been BI_ADD()'d, because the bootloader
might need to re-BI_ADD() if the bootloader have to try to boot a few
kernels (netbsd, ..., netbsd.gz) before finding one.
A better place to protect against BI_ADD()'ing the same BTINFO_* twice
is in bi_add().

nope.
I installed patched /boot and bootxx_ffsv2 but the kernel
on wd0f still mounts wd0a as root partition.

Woot!
The kernel with your patch boots from expected partition.
I revert /boot and bootxx_ffsv2, then boot the new kernel
with '-a'. It shows certainly wd0f as root dev.
Thanks again.

Is anyone working on this?
Shouldn't this be committed and pulled up to 6.1?

It seems done by christos@
http://mail-index.netbsd.org/source-changes/2013/04/28/msg043382.html
BTW, the submitter said he didn't use wedge but met the problem.
Does that mean BTINFO_BOOTWEDGE is always setup by /boot for any disks?

Could anyone please request pull-up this fix to netbsd-6?
