Indeed. Of course, it would also be nice if distros shipped
bootloader-invoked prekernel test software, like memtest86+, by default.
the current memtest86 is running in 32 bit mode, and only support 64G ram.
I tried to expand that a bit, to support 1024g, but it only works on
some machine.
could be stack provide is not big enough?
