I just observed this failure on two separate systems this morning. I
added the patch in the hopes that it will provide some useful

This could be a hardware problem. Or it could be a bug basically
anywhere
in the kernel.
Are you using CONFIG_DEBUG_SLAB?
Could you please apply the below patch, wait for the problem to reoccur,
