In this particular instance it turns out (most likely) to be an
overheating issue -- once I removed one of my two RAM modules
everything is more stable. So noapic is not the culprit in this case.

It might still be useful to have such a database, so
1) users of affected hardware don't spend too much time diagnosing the problem
2) kernel developers have a single place to look for compatibility issues
