Upstream v4.7-rc2 kernel does not boot if parameter acpi is set to force
on Overdrive. (acpi=off gets to the prompt)
When set to force it doesn't get to the Linux boot process and stalls.

Here's the BIOS info:

Did acpi=force work on this board with an earlier kernel (e.g. v4.6)?

What output do you get before it stalls?

I assume that you at least have output from the EFI stub?

Which command line options are you passing?

If you get nothing after the stub, try also passing:

earlycon=pl011,0xe1010000

Which may give an indication of what's going on.

I don't know if the FW from a year ago provided everything necessary. It
may be something like the SPCR is simply missing, and there's no
console= passed to the kernel.

Thanks,
Mark.

v4.6 boots fine with acpi=foce.

Yes.

At the time of trying, only acpi=foce efi=debug

Adding it in the /etc/default/grub file and updating grub via
mkgrub2-config seems to made the board always falls on the grub prompt.
I am able to switch to the EFI shell, but is there an easy way to 
recover it? (I'm accessing the board remotely)

Do you get anything else? A full log woould be helpful.

If you can open GRUB, press 'e', and you can edit the command line.

If GRUB doesn't work at all, you might be able to use the 'edit' command
to modify the GRUB onfiguration file.

Thanks,
Mark.

make defconfig
make Image.gz

Seems to boot fine here

cat /proc/cmdline
BOOT_IMAGE=(tftp)/arm64/Image console=ttyAMA0
earlycon=pl011,0xe1010000 acpi=force r8169.use_dac=1 ip=dhcp
root=/dev/nfs nfsroot=192.168.10.253:/srv/nfs/d02-debian rw

uname -r
4.7.0-rc2

Thanks

Graeme

Hi Mark,

Thanks for the recovery suggestions. EFI edit couldn't read the
grub.cfg for some reason, so I decided to do a clean installation.

Here's the v4.7-rc2+ kernel boot log (earlycon=pl011,0xe1010000 
acpi=force efi=debug):

It looks like the we're failing to find the console (judging by the fact
the kernel opted to use a dummy device). The other messages look largely
fine. It may be worth also passing "keep_bootcon" to try to get a few
more lines of messages, though that may or may not be helpful.

I was under the impression that SPCR told us the console to use, but
from grepping the kernel source code, it looks like mainline doesn't
support that yet. Given that, I'm at a loss as to how this could have
worked for v4.6.

I take it you've used the exactly same command line for v4.6 and
v4.7-rc2? i.e. you weren't previously passing something like
"console=ttyAMA0,115200"?

Were you using a vanilla v4.6? Or some distro derivative?

Thanks,
Mark.

I tried that and actually I obtained a lot longer boot log, I will past 
it below after answering your questions.

I doubt I was, but as I've reinstalled the system there's no way
to confirm.

It was a vanilla v4.6.

Here's the log file, the v4.7-rc2 kernel is built with defconfig this time

Ok.

I just had a go booting a v4.6 kernel (defconfig + CONFIG_EXPERT to
enable the relevant ACPI options) on a Seattle system. I passed
"acpi=force", but avoided "console=". 

The last messages I see form my kernel are also:

[    0.008104] Console: colour dummy device 80x25
[    0.012572] console [tty0] enabled
[    0.015989] bootconsole [pl11] disabled

If I also pass "console=ttyAMA0,115200", I get a full set of messages,
including a i2c-designware-core warnign similarly to what you saw below
for v4.7-rc2.

So I suspect previously, something was passing an option like
"console=ttyAMA0,115200" to the kernel.

Thanks,
Mark.

Applying relevant series from Aleksey and Leif in the leg-kernel tree on 
top of v4.7-rc2 works. (commits 1512e71bdcf and 3df2702192e42)

Many thanks to Graeme for catching up the development.
