Public bug reported:

Hello,

I faced a problem where readyRead is not fired for QUdpSocket.
I've tested this functionality with a basic udp receiver on different systems.
On armhf it works fine, the same code does not work on arm64 (Pine64).

This seems to be similar to bug https://bugreports.qt.io/browse/QTBUG-48556 mentioned on QT site to be fixed with 5.5.1
Maybe it was not merged to arm64? Or any other idea?
netstat -l shows that bytes are available

With polling implementation it's possible to receive the data.

Ubuntu 16.04.1, all updates
Pine64, arm64
Kernel: 3.10.102-2-pine64-longsleep

Best regards,
Alex
