I’ve been looking a little more closely at what’s different in the initial output from the RTEMS tap files that pass vs failing on GHA. In all cases I’m using epicsTypesTest. The results aren’t earth-shattering, but they might tickle some thoughts.
This was from the last GHA build which passed all its tests on RTEMS-4.10.2, the 7.0.6 tagged release:

Here’s the GHA output from the RTEMS-4.9.6 build of the latest commit. These tests that we have full results for all pass, but the total time needed to run the tests exceeds the 20 minutes we allow for the testing phase.

We don’t currently run the tests on GHA for RTEMS-5 builds because the OS is so slow to start. This is the output on my RHEL-7 box, note that RTEMS was built with the new network stack:

Finally I built the pc686 BSP using the legacy network stack instead of the libbsd one and recompiled EPICS against that. The build failed in the network configuration code:
Oops, something changed… This patch may be wrong, but allows the build to complete (in modules/libcom at least):
With that the tests connect to the ne2k interface and get an IP address, but they hang before actually running the test code:
