There are also other causes of "BUG: soft lockup - CPU#n stuck". One of them
is bad RAM.

You can diagnose bad RAM more reliably through 'memtester' [1]. That did it
in my case (on an x86_64 machine): Ran memtester to prove that I had bad RAM.
Then replaced the RAM. Then the "BUG: soft lockup" errors were gone.
