5.7.7 kernel was still unstable, so was 5.8rc3, but at least with the latter it logged some information that showed some memory allocations failed with the contiguous memory allocater, a new feature recently introduced into the Linux kernel.

     I am building a new kernel with that disabled, it really isn’t required since there are no huge streaming I/O devices like video that might require it and most everything can DMA through the MMU on this particular machine (which can map disparate memory regions into contiguous memory).  If it does not spontaneously boot into the new kernel, I will boot it this evening.

     There is also the possibility of hardware errors but so far it has not logged any.
