Posting to list as requested. I get call trace when using WiFi on
Khadas VIM Pro, which comes with an AP6255. Firstly i wrote about this
directly to Martin Blumenstingl, and he pointed me to post here.
This looks like a bug in the meson-gx-mmc.c (SD/SDIO/eMMC) driver .
Martin last successful test was with kernel 2.11.
How to reproduce this:
mainline kernel 4.12.0-rc3 (using ArchLinuxARM arm8v generic rootfs)
Khadas VIM Pro nvram file 
Enable WiFI (connected to 5GHZ AP)
just do an SSH to Khadas VIM Pro device and you will get these call
trace  , eventually you get login prompt but it is very slow login.
