The type of errors I am talking about are random bit flips, for instance, from ambient radiation. When the OS reboots it will overwrite memory and so remove those errors. The affected cells were not damaged, just in the wrong state. This should work so long as none of the damaged bits prevent kexec from doing its job. Presumably the OS will also reinitialize all memory structures stored elsewhere in hardware (as in storage controllers and NICs) since it should not trust the BIOS to have done this.
