It would look as a repetition of the JDK-8288907 or JDK-8294741, if not for the huge timeouts - more than 2 hours and the fact that linux-x86 does also show the problem.

The log is laconic:

This deadlock issue has the same symptom as JDK-8353496 as one of TestThread* virtual threads can not be started by scheduler. Closing it as a dup of JDK-8353496.
