Package: src:linux
Version: 5.10.24-1
Severity: important
Dear Maintainer,
* What led up to the situation?
I used the tool debos https://github.com/go-debos/debos to create a
debian image on my machine. debos uses qemu to setup an install
environment for debian. After a while the process got stucked.
* What exactly did you do (or not do) that was effective (or
ineffective)?
* What was the outcome of this action?
I got a kernel warning
