It's kind of hard to run anything over SSH if it has to be run before
userspace is up. But the kernel can collect results from a modified
memtest, after it chains back.
1) if linux fixes some problem with PCI quirk or microcode
upload, memtest will not see the fix
What are you saying? Linux is going to fix faulty RAM? The point with
testing RAM is you *want* to see it fail; you don't want Linux to fix it.
2) if memory only fails while something else happens (DMA to
other piece of memory? Hard disk load glitching powre
supply?), memtest will not see the problem.
These are not RAM faults. The very last thing you want is evidence that
you've got a faulty piece of RAM when the fault is actually a hard disk
glitch!
