Bug Description
Ryzen 5 3500U (release in 2019) won't boot when laptop is on battery power. It affects different brands of laptops. Laptop boots normally with charger in and you can unplug the charger and then use battery.
For some a work around is possible on kernel 5.4. For others kernel should be 5.5 or better yet 5.6.
issue described in more detail in Ubuntu forums: https:/
dmesg: https:/
iommu=soft boot options provides the work arround on some laptops, while on others USB ports stop working.
OS: Kubuntu 20.04 LTS
CPU: Ryzen 5 3500U
GPU: AMD Vega 8
RAM: 8 GB DDR4 2400 Mhz
disk: 256 GB nvme
I patched kernel (now tainted) to get driver for rtl8821ce (wi-fi).
affects: | ubuntu → linux (Ubuntu) |
