Comment 9 for bug 1838176

I am facing the same issue with ThinkPad-T495 5.3.0-26-generic (ubuntu 18.04). I have seen a subtle nuance to the issue. I can successfully boot every time I am powered on. But this issue only occurs when I am on battery.

I tried the suggestion by Soedarsono (Comment #7) but the situation has not improved, unfortunately.
I got the following warnings.

"
update-initramfs: Generating /boot/initrd.img-5.3.0-26-generic
W: Possible missing firmware /lib/firmware/amdgpu/vega20_ta.bin for module amdgpu
W: Possible missing firmware /lib/firmware/amdgpu/navi10_mes.bin for module amdgpu
"

Could this be a problem?
