Solved HP Compaq Elite 8300 SFF can't wake up from sleep

Hello,

I'd like to use FreeBSD on a HP Compaq Elite 8300 Small Form Factor. Unfortunately, I can't get working sleep/resume, neither S3 (suspend to RAM) nor S4 (suspend to disk). I don't care about S4, but I definitely need functional S3.

The machine is booting FreeBSD 13.0-RELEASE-p5, root on ZFS, in UEFI mode.

Running acpiconf -s 3 works as expected, but resume fails: when I press the power button, the computer powers on for a very short time, then powers off again and reboots.

This isn't related to DRM: the machine has nothing but Intel integrated graphics, and the problem is the same with and without drm.ko and i915kms.ko loaded.

Other operating systems (NetBSD, OpenBSD, Linux) aren't affected.

What can I try?
 
Depending on what you use it for, I just wouldn't let it sleep. Also, have you tried paying attention to how acpiconf -s 3 even works under other systems? The other systems probably have some different defaults than FreeBSD. If you get those defaults copied over to FreeBSD, you might be able to figure it out.
 
It's meant to be used as a desktop machine, so, well, no sleep at all isn't really an option.

Do you have an idea what kind of settings I should look for? I'm not familiar with ACPI stuff.

As additional information: loading acpi_hp.ko and/or acpi_video.ko doesn't make any difference.
 
In that case, I'd suggest looking at acpiconf(8) and see what other places it points you to. Great way to start exploring.

And in reference to some trolls we've seen recently, the forums are always there to help along with such explorations, make sense of info we come across, and help arrive at meaningful results, even if the results are different than the original goal. :p (This part is aimed more at everyone else who might be reading this thread).

If you like, I can let you have a copy of a file that you can copy to e.g. a suitably formatted USB flash drive, then update the BIOS (from that file) before booting an OS.

That would be nice, because I don't have a Windows system to run that .exe updater!
 
For comparison, I tested with 12.2-RELEASE and 14.0-CURRENT, as well as booting in legacy BIOS mode: it didn't work in any configuration. The only noticeable difference was with 14.0, where instead of an almost instant reboot after resume, the computer would stay on, but without outputing any video signal.

As far as I recall, not so with 8200 and 8300 SFF.

Write it to the msdosfs file system of a non-partitioned drive. (The update routine might not find the file if written to a partition of the drive.)

Code: 
% gpart show da2
gpart: No such geom: da2.
% lsblk da2
DEVICE         MAJ:MIN SIZE TYPE                                          LABEL MOUNT
da2              2:33  1.9G -                                                 - /media/General_UDisk_
% mount | grep da2
/dev/da2 on /media/General_UDisk_ (msdosfs, local)
%

I do have other files on this drive, but I don't recall them being required for the routine that you'll run.

Done, thank you.

Upgrading from that file doesn't work, it seems I have to upgrade to v.02.99 first:

Thank you sir! Now I have an up to date BIOS.

Unfortunately, still no luck with resume. Anything else to try?

An 8300 SFF desktop will pass through my hands in the near future (I might gently chase the customer today).

If I can find time, out of hours, to temporarily put in place a disk with FreeBSD (probably 14.0-CURRENT): I'll let you know what's found. I do have a readily available installation, but it's on a mobile hard disk drive. Not suitable for sleep/wake.

In the meantime, maybe try x11-drivers/xf86-video-intel.
 
Just curious, did you try 14-CURRENT with i915kms ?

Also, could you please set debug.acpi.suspend_bounce=1 before a suspend?
This should help to understand if the problem is in one of device drivers or somewhere deeper in the ACPI suspend/resume code/

I meant, the mobile hard disk drive is not suitable because it's on USB.

When I last checked, FreeBSD lacked the required support for USB.

I guess this is the difference between US English and GB English... "mobile hard disk drive"... I would have never guessed that really means "USB stick". Most of them are really SSD's rather than HDD's, but it's not impossible to find a USB to SATA adapter, and attach an HDD to that... 😅

I didn't until now and this... works! Do you think there is any chance to get it working the same way on 13.0-RELEASE?

Back on 13.0:

This works fine.
Here's my dmesg from just after trying this:

The problem does not look like it's related to any particular driver. Seems to be something in the ACPI code or in the platform code (like multiprocessor support, etc).
So, most likely would not be easy to identify what exactly needs to be merged form 14 to 13.
