- Message-id: <156088691951.13749.1185589861406665177.reportbug@localhost>
Package: linux-image-4.19.0-5-rt-arm64
Version: 4.19.37-3
Severity: normal
Dear Maintainer,
*** Reporter, please consider answering these questions, where appropriate ***
* What led up to the situation?
Install linux-image-4.19.0-5-rt-arm64
I installed the unofficial image from debian arm64 on my Raspi 3. Then i played
arround. all seemned stable. Then i installed connman and the system started to
OOPs.
It does not always occur, just on ever 2 or 3rd boot.
See attached bug.log that i captures through tty.
