Oh no!

Well, now you probably know what the cause of the hangs is.

This is something of a long shot and the thought gives me unwelcome
flashbacks to 1980s hard disk  setup and hand-entering bad blocks
lists, but...

Memtest _can_ sometimes tell you the region where the errors occur.

Linux can take a kernel command line telling it to exclude some known bad RAM.

*If* it is one bad region _and_ if you can identify it, you could
potentially map it out and then make the system more stable 'til you
can buy a replacement.

Quite a big "if" though.
