I built a new netbsd-8 kernel (with source from about the same time as
the binaries I used to install) and the only difference from GENERIC
is I enabled PAE in the config.

It now runs fine with smp and acpi enabled.

No idea why it was so unstable before.

Yes, the machine is nearly unusable when booting with SMP (I think). I
booted it with -1 -2 last night and it's still running this morning.
All it has done is a few cvs checkouts and updates though.

Another detail, not sure if it's related:

I have a wm network adapter and performance with it was horrible, I
was getting +4000ms pings to my gateway on a wired gigabit network. I
switched to USB3 gigabit adapter (cdce) and things are working
normally.

I am checking out -current right now and I will build a kernel and report back.

There are no PRs about this recently, I'm willing to open one for this
panic if this will help.

No, the recent changes (that make -current pretty instable right now)
have NOT been pulled up.

I'm actually using netbsd-8 from the 201711131530Z directory on nyftp.
I downloaded the install kernel from there and then did a full install
from the ftp site.

I tried booting with and without -2 and I'm not sure if it affects the
new problem I'm having.

I booted the install kernel and mounted the root disk and did sh
MAKEDEV all in /mnt/dev and it seems to have got me past that point.

Now I see "white" boot messages, but it sometimes hangs in fsck,
probably on /dev/rwd0e which is /usr. This happens if I use the
generic kernel I just installed or with the install kernel and do fsck
manually on /dev/wd0e.

Here's the hokey part. Sometimes ctrl-c hangs. Sometimes it dumps me
back to a prompt. Sometimes it panics.

If I boot with "boot -1 -2" it seems to solve the hangs during fsck,
but I'm not 100% sure about that.

I took photos of the panic at:

http://acruhl.freeshell.org/netbsd-i386-8-panic1.jpg
http://acruhl.freeshell.org/netbsd-i386-8-panic2.jpg

I think this is SMP related, but I'm not sure.

I got 2 panics that looked pretty similar to this when I did ctrl-c
during fsck which seemed to hang.

Hi Andy,

If you have a PS/2 keyboard you should be able to use ddb
(ctrl+alt+escape), and see where it's stuck.

Another option is boot -d (in the boot prompt) if I'm wrong about the
string to enter ddb.

NetBSD- (Beta) will have a newer ACPI in it than your old -7 kernel.

That's the last of the normal kernel printfs during boot, at that point,
init should be running, and running /etc/rc

If I had to guess, I'd say that your /dev/console isn't correct, as the
next messages should be appearing there.   Check what's there (using the

Ok, I sort of got past that but it might still be an issue.

This is what I've done so far:

Booted the Netbsd-8 installer, used the /bin/sh prompt to mount the
internal disk and configure a USB network interface.

I put an install kernel in the root of the boot disk and rebooted.
Interruped the bootloader and booted the install kernel.

Before the reboot I unplugged all disks except the root disk, which is
partitioned "old style" with separate partitions for /, /usr, /tmp,
and /var

The installer complained about the disks it couldn't find but
eventually I upgraded to netbsd-8.

I rebooted and confirmed that it works (other than complaints about
the disks which don't exist). ACPI appears to be working.

So now it hangs here:

http://acruhl.freeshell.org/netbsd_wont_boot2.jpg

(last message is kern.module.path=/stand/i386/8.0/modules)

I don't know what's happening at this point.

The intent was to disable it in NetBSD via the boot prompt - but that
is only possible if your boot.cfg (on the netbsd-7 root) was set up to
give the menu and wait a few seconds for you to interrupt.

If you don't have a menu entry for booting with ACPI disabled, you should
still be able to boot manually from the boot prompt, just give
netbsd the "-2" option.

I got a few private responses, thanks for that.

Some more notes:

I can't seem to make this motherboard's BIOS disable ACPI.

>From here I have sort of "chicken and egg" problems.

I wrote a i386/8.0 installer to a USB stick and it boots past the
kernel (so no ACPI issues), but it wants me to tell it what root disk
to use. I thought it would want to use the USB stick as the root. It
only allows me to give it "wd0a", which has a netbsd-7 userland and no
modules, so it just dumps me to a sh prompt.

Found out I need to tell the USB stick's bootloader to disable ACPI
and use no SMP (not sure about SMP though), then it boots semi
properly.

>From the /bin/sh I can't do "anything" though. I plugged in another
USB stick with an 8.0 install kernel, but I can't figure out how to
mount it. mount -t msdos /dev/sd1{a,d,e} /mnt doesn't work (Invalid
argument for sd1d, others don't exist). Also, ifconfig only shows lo0,
so no network adapter. I'll try putting another one in.

I guess I could try netbooting using PXE from the BIOS. Was hoping it
would be easier to get to 8.0 than that though.

Still working on it.

Try disabling ACPI. There is probably an option in the bootloader menu
to do that.
