Hmm... Would it trigger on Orangepi5plus? With some effort I can get that 
board up at home.

Could you reboot with some memory diagnostics so that we are sure that 
nothing gets corrupted?

F.e. specify a command line parameter "slub_debug" to enable redzoning. 
That way we may see potential memory corruption.
