Just wanted to update that I tried kill -QUIT (or kill -3) and there wasn't
any thread dump as a result.
It seems the deadlock appears so deeply, that it basically hangs even the
basic routines.

Again, if there any way to convert these ?? symbols in GDB dump to actual
function names, it would greatly help discovering the culprit.

Will appreciate any idea on subject.
