Allwinner A64 RTC bug fix on bionic image?
#1
Hello,

I am working on a Pine 64 LTS board. I am using the Ubuntu image bionic-minimal-sopine-bspkernel-0.7.30-140.img.

I recently stumbled on the problem described in this patch:
https://patchwork.kernel.org/patch/10392891/

My question is, that does the image i am referring to have the timer instability issue taken into account in some way?

I ran the test provided in 
https://github.com/apritzel/pine64/blob/...st_timer.c 
and i had no errors.

This would imply that the fix is implemented either in the kernel or in the SoC.

Can anyone verify this for me?

Sorry if this subject has been discussed before, but i had trouble searching with the keywords "rtc bug".

As my understanding, this is a glitch on RTC design and only occasionally happen. For more detail, please check the Linux-sunxi IRC log for more info.
