BIOS Acer Revo Nettop M1-601 / M1601 - Ubuntu drivers plus BIOS limitation

whiteduck22 · March 2016

Hi all,

Two questions on a fairly new model that appears to have little information available from Acer or the wider Internet...

The M1-601 Nettop (Sold on ebuyer.com in UK as M1601).

1. I installed Ubuntu 15.10 and have had some trouble with

- Sound not working via the headphone jack

- Instability with the graphics adapter causing a stack trace and then a blank screen while sshd still allows connections

- General instability - nothing in /var/log

2. I had hoped to be able to set the power option to resume last state after power failure as this is intended to run 24x7 - but the BIOS is locked - any clues?

With thanks

Ian

Here is the Stack Trace I see when I touch the keyboard and wake up the monitor (HDMI):

Another update - seems to be a kernel bug so I added this option to grub which so far has made things stable... let's see if I get beyond 36 hours:

GRUB_CMDLINE_LINUX_DEFAULT="intel_idle.max_cstate=1"

whiteduck22 · March 2016

For info this fix has resolved the stability issue (I think)... been up now for over 3 days...

So to resolve:

BIOS! I hope this is fixable and that I can change the power resume setting.

Video and sound driver issues.

cdc · March 2016

Did you manage to install to the EMMC HBG4e 32G drive?

I've not been able to find a installer that detects this disk, I have tried several versions of Debian and Ubuntu but none of the installers can see this disk.

whiteduck22 · March 2016

Yes Ubuntu 15.10 server installer had no trouble.
Be sure to implement the fix above else you may get instability.

Good luck
Ian

whiteduck22 · March 2016

On and i chose Legacy instead of UEFI in the BIos.

cdc · March 2016

How odd, Ubuntu 15.10 server didn't detect the 32GB EMMC drive, I could see it in the BIOS but not during the

install.

Also I had to edit the grub command line to add `noapic` to get it to boot. With some install attempts I also needed `edd=off`.

I have ended up running the machine off a USB thumb drive.

Could you post the details of the disk from `lshw` and any other information you have so I can try to detect the disk and install to it?

whiteduck22 · March 2016

Sure will do - I wont be home until Sunday night

You don't think it was UEFI vs. Legacy - if I change to UEFI now it can't find a boot device?

cdc · March 2016

It defaulted to Legacy in the BIOS and I haven't changed it, the only thing I changed in the BIOS was the boot order.

The machine is now running headless in a cupboard, but next time I have a chance to connect it to a HDMI device I'll try UEFI and see where I get to...

whiteduck22 · March 2016

Yeah mine is on default of Legacy so that can't be the problem. If you are running headless then I guess having a useful Bios with restore previous power state is useful to you too. Let me know if you find a way to get to the advanced menu.

whiteduck22 · March 2016

I added some RAM hence the 8GB. I don't see the eMMC in the lshw

Thanks for all that info!

I don't have the /dev/mmcblk0 device, so I guess that's where I need to start...

whiteduck22 · March 2016

Very welcome!

In the meantime Acer Support (who are very helpful) confirmed there is no unlock option for the BIOS... which means unsupported options only... anyone got a fix? Thank you!
