Any chance that the file system where the trace is is full? As you already changed the diag dest this is not very probable. Other slight possibility: have you checked elsewhere for the alert log, somewhere underneath ORACLE_HOME?

Strangely enough, the log.xml in the alert directory of the diag destination is being updated normally, it is just the plain text alert.log in the trace directory that is not updated. We have bounced the database, changed the diag_destination parameter and I have even grepped all the file descriptors in /proc/*/fd for traces of a possibly opened alert.log - nothing, the alert.log is still not being updated. I tried dbms_system.ksdwrt to force a write to the alert.log - again, the log.xml is updated, the plain text is not. My last resort was to file a case with Oracle Support, and they are having me redo everything I have already done, even though I stated up front that I did all these things already (see above).

What could possibly explain why the alert.log is not being written to? It looks, smells and feels like there is an underscore parameter that prevents writing to the alert.log. But Oracle Support is telling me no such parameter exists (and I have not found one).
