1. Suspect bad RAM.
2. Run e.g. memtest86 from its floppy.
3. Note locations of bad bits, if any.
4. Add those values to the vm.blacklist setting.
5. Repeat until there are too many bad bits to justify keeping the
stick any more.
It would be great to have something even more convenient, like a RAM
test at boot time which automatically appends its findings to the
vm.blacklist. That would be correspondingly more work to implement, of
course...
