    Frequent dead freeze with AMD ryzen 2500u laptop.

    I recently got an Acer Swift 3 powered by AMD ryzen 2500u and currently setup with Ubuntu 18.04 LTS. I get frequent dead freeze on the laptop, at least 2-3 times a day, where even ALT + PrntScn + REISUB also doesn't work. I tried upgrading my kernel to 4.17.2-041702-generic also, still no avail. Please help with this. I did a
    Code:
    journalctl --since "1 hour ago"
    but the error seems to change from crash to another. Here is the log - https://pastebin.com/wJWY7RNg (crashed around 17:06). Thank you for all the help.
    Has been months since I have posted this, still, haven't found a solution to this.

    I also got freezes on my Thinkpad E485 with the Ryzen 2500u. Furthermore I've all updates installed (Ubuntu 18.04) with the newest stable kernel v4.17.8.
    In the kernel options, at the grub start options, I added "noapic" and "idle=nowait" but no improvements (but I had to add "noapic" to get Linux even to boot with the 2500u).

    I hope this will help for others. I have a thinkpad e485 with a ryzen 2500u. After trying lot of solutions I finally found the problem. Just disable CPU Power Management in BIOS did the trick for me. My Thinkpad runs now for 3 days without reboot. Before that I had freezes like 4 times a day.
