So I installed Fedora and am testing kernel 4.18rc1.
It seems the issue has not been fixed yet. I will start testing with what kernel parameters are needed for this.
In the meantime, 4.17 works perfectly with the two parameters I posted two weeks ago.
Thank you guys for investigating this issue when AMD doesnt.
I recently bought an Acer Swift 3 with Ryzen 5 2500U and installed Linux Mint 19 on it.
Using latest Kernel 4.17 and Mesa version but Im still having the same freeze issues when watching youtube videos. I will try the suggested workaround and report on it.
I was able to work on my notebook this evening without a single freeze. It seems, for my case just adding processor.max_cstate=1 in /etc/default/grub was enough:
I have the same machine and I hope this will help me.
At the same time I am wondering, how did you manage to install LM to it? Mine wouldn’t play ball at all with LM. It didn’t even get into the desk environment from the USB.
I am currently running Antergos Cinnamon and liking it a lot.
Thanks for the solution, will let know if my system holds.
I forgot where I found this, but appending “idle=nomwait pcie_aspm=off” seems to keep the laptop running even better than my previous solution. Can everyone please try and confirm my findings? I have not run into any crashes yet on kernel 4.18
AFAIK this seems to be a BIOS issue.
So, after an adventure with the lenovo support via twitter (don’t ask, it wasn’t pretty…) I have now the last BIOS version on my 720s-13ARR that is available for it. I installed kubuntu 18.10, installed kernel 4.20 and set processor.max_cstate=1 as well as pcie_aspm=off and so far it seems to be stable.
So i have a Acer Nitro 5 with a Ryzen 5 2500u and in order to get into linux. i have to add noapic to the grub boot flags. id try adding that to your grub config
I just updated my BIOS to F.20 on my Envy x360 15 inch with Ryzen 5 2500U
I booted with no extra parameters and did not disable C6, it seems to be running just fine, but only on Linux 4.19
Whenever I try booting Linux 4.20 or 5.0rc, it just freezes on boot. Did anyone try 4.20 or 5.0rc?
I’m using a Thinkpad E485 (Ryzen 5, 2500U) with linux-amd-raven kernel (based on Linux 4.20)
The kernel parameters I’m using are noapic and iommu=soft. I believe the 2nd parameter is needed for Linux 4.20. Got this info from the arch wiki (https://wiki.archlinux.org/index.php/Laptop/Lenovo#E_series). This config seems to be working for me so far (2days).
Haven’t tried 5.0rc, maybe you could try these parameters and test it?
I think I found the fix, it seems to be an issue with the firmware, not the kernel. Try downgrading your firmware blobs to a previous version. On Arch, it seems the October releases work just fine with 5.0rc5, but I can’t boot 4.20 regardless.
