A true mainline Linux Kernel for the Pinebook Pro

[timmes]

s3 also doesn't seem to work with the presence of an NVMe device.

I'm having the exact same issue as other users are describing, with a 256GB WD SN520 NVMe SSD. Appears to go to sleep, then comes straight back.

dmesg output:

I think

Code:

rockchip-pcie f8000000.pcie: PCIe link enter L2 timeout!

Is the critical part here, especially as it waits a couple of seconds before this happens. lspci -vvv reports ASPM L2 is not supported. That could be a crucial difference with the NVMe SSD's that do not have this problem? If anyone who has this working could post their lspci results that would be great. Either way this SSD suspends just fine in a regular laptop.

Enabling ASPM power management works fine by the way (and appears to actually save ~250mW, but it is kind of hard to measure), but it doesn't make it work either way. Haven't tried forcing it off with the kernel parameter yet.

Running a stock 5.6.0-2-MANJARO-ARM kernel.

I'm more than willing to try out some suggestions. The Pinebook Pro is a great laptop especially because it is so easy to charge from existing 5V infrastructure (like USB sockets in public transport), but having to shutdown and restart every time is a major PITA. I'll have to remove the SSD if this cannot be fixed.
