armbian for Orange Pi Zero Plus 2
HiI know I'm sort of cross-posting... but i wanted to see if anyone attempt to build the kernel of armbian for the Zero Plus 2?I'm encountering below instability, the system crashed randomly with Insufficient stack space to handle exception!I'm trying twaek on different build configurations and see if I can locate the issue. there're lots of build options, and I'm sort of hit and miss....
Any ideas?

+1, please help I've just posted it in armbian forum. I've found that the CPU clock is keeping at 1152Mhz, that have caused the random restart. I set the highest CPU to 1000Mhz and it keeps running at 960mHz and it's stable. Looks like the current step up/down on the ondemand governor does not work well yet.
Anyway if you need it to run stable, lower the CPU clock. @sywong2000 I am with the same issuea and thanks for your post. How can i lower the CPU clock? I am newbie on armbian. You can limit it with editing /etc/default/cpufrequtils any restarting this service or reboot. @igorpec. Thank you, but the issue persist. I already change the microsd, power supply and remove the expansion board, but this sh*t board dont work. Any other suggestion? Any other suggestion?
Changing to the beta repository and switching to latest DEV kernel (4.17.y)
