ARM64: Allwinner H5 crashes after few hours (NanoPI NEO2)

[Domenico Andreoli]

Hi,

  I'm running Debian Buster (kernel 4.15.4-1) on a NanoPI NEO2, Allwinner
H5.  It's a new installation and I'm now hitting some stability issue,
I've not any prior stable kernel to compare with.

The one below is the first capture of the fault in action. Is anybody having similar issues?

Kind regards,
Domenico
