ROS 2.9.44 failing to reboot

Setup: A pc (gigabyte mboard) with 512mb cf drive. A rb14 with 2x cm9 and 1x r52.

From powering on the pc-router it boots 100%, rebooting from console or winbox with 1 of the cards in “AP Bridge” mode. It hangs at “Starting …” and goes no further. Even a reset of the mboard doesn’t help, it has to be powered off and on again for it to boot. Any ideas ?

edit: If all the wifi interfaces are in “Station” mode it reboots fine.

Update:
Plugged cf-drive and rb14 into another motherboard. It has the same result, any ideas ?

Any possibility that you can test the router with another RB14 or even an RB11.

Would like to know what the answer to this problem is?

after testing all the radio cards with a rb11, its a faulty rb14…
