Hello ma dudes

Just got the Acer Nitro 5 and i want to install ubuntu on it and ive gotten no luck. Ubuntu will not boot. The error that i keep getting is WATCHDOG bug cpu hung up. attached an image of it. I have tried different releases of ubuntu 16.04, 17.04, 18.04 and suggested by Wendall on twitter 18.10 and i have added boot flags to grub like nomodeset and nouveau.modeset=0 and it wont work.

Fedora will boot but not pick up any trackpad drivers.

Any ideas or question please just let me know

Regards

Lenovo ThinkPad E585 - Ryzen 2500U/Vega 8 - Review, Impressions, Linux, etc Laptops & Netbooks

Hey all. I picked up the ThinkPad E585, thought I would do a mini review of the laptop now that I’ve had some time to play around with it. This will not be a thorough review, just some general thoughts and info. I intend to edit it as I continue tinkering with it. Specs: Ryzen 5 2500U with Vega 8 Mobile graphics 16GB (8+8 dual channel) DDR4 2400 256GB m.2 NVMe SSD (mod) 500GB SSD for dual booting 1080P IPS TL;DR: I like the laptop. Good build quality, decent display, good performance. Battery life isn’t great… around 4 hours give or take. Linux works well with the latest kernel/mesa… only bluetooth doesn’t work. Full lshw output here: http://paste.ubuntu.com/p/6WVhFQygKn/ Full lspci -vvv output here: http://paste.ubuntu.com/p/g7FP5nN9JX/ [image] [image] [image] [image] [image] [image] [image] [image] Note: I got cinebench GPU score slightly over 40 on another run… not pictured here. Here are some general thoughts: Chassis/Build Quality: Very happy with the laptop in terms of quality. It feels very solid, no creaks or pops, no keyboard flex. Everyone seems to complain about the E-series thinkpads being cheap but I was pleasantly surprised. Top is aluminum, the rest is plastic. The lid does attract fingerprints pretty bad, but it’s not a big issue. Keyboard/Trackpad: Disclaimer: I’ve never used a laptop with windows precision trackpad drivers, so I can’t compare to that. This laptop uses a synaptic trackpad and it seems to track well. Everything works as expected in both Windows and linux. Clicking feels VERY nice on the bottom trackpad buttons… it’s like a muffled clicky sound which is really satisfying. Difficult to explain. I like the keyboard a lot. Th…

Those flags are still giving me the same issue

FurryJackman · October 5, 2018, 9:00pm

You may need to turn off ACPI entirely. acpi=off or pci=noacpi as per here:

A Windows based BIOS update might be needed too.

AcidzDesigns · October 5, 2018, 9:06pm

i have already updated it to the latest bios as well

AcidzDesigns · October 5, 2018, 9:10pm

alright alright, i got into ubuntu with nomodeset and acpi=off

digital_zero · October 5, 2018, 9:10pm

I’d try a distro with a newer kernel if you’re still having issues. I’m not sure as I don’t own that laptop though.

AcidzDesigns · October 5, 2018, 9:11pm

Tried a beta release of ubuntu, same issue

Goalkeeper · October 5, 2018, 9:12pm

So everything works now? Or are there still things that don’t work?

AcidzDesigns · October 5, 2018, 9:13pm

just got purple screen

digital_zero · October 5, 2018, 9:14pm

What kernel does the beta use? I know ryzen apus like the 2500u are having issues on everything short of 4.18.

digital_zero · October 5, 2018, 9:17pm

Nevermind it’s 4.18. maybe try the 4.19 release candidate?

AcidzDesigns · October 5, 2018, 9:17pm

Ok i get the purple screen, stuff loads and then it kills power. no idea

AcidzDesigns · October 5, 2018, 9:17pm

link?

digital_zero · October 5, 2018, 9:22pm

To the kernel? You’d probably have to boot arch or something and pull down the release candidate to test. I’m not sure how to get it via Ubuntu.

digital_zero · October 5, 2018, 9:23pm

This is the post talking about it

First time post here on this forum for me. Found this post and wanted to help out

Doing the grub edit from this blog post worked perfectly for me. Currently typing this from my Lubuntu 1804 install.

I had a succsess from this post here: Ryzen/Vega laptop PCIe Bus Error

Open terminal and write sudo nano /etc/default/grub and add processor.max_cstate=1 to GRUB_CMDLINE_LINUX_DEFAULT line so it reads:
GRUB_CMDLINE_LINUX_DEFAULT="quiet splash processor.max_cstate=1"

Then don’t forget to update grub sudo update-grub.

That helped me on my Acer with Ryzen 5 2500U.

is there any update on working ubuntu with ryzen 2500u without the tweaks, i had to set “noacpi” which results in weird fan and processor behavior. Processsor is continuosly in full load and the ui experience is not very smooth.
