Package: linux-image-amd64
Version: 6.1.20-1
Severity: important
X-Debbugs-Cc: tim.rueh...@gmx.de
Dear Maintainer,
* What led up to the situation?
We run a priviledged eBPF based tool with a communication between kernel and
user space.
It runs without issues on kernels 4.15 to 5.18.
On kernels 5.19+, the whole system freezes after a few minutes.
It seems that with more system activities (load, forks) the freeze happens
earlier.
The underlying hardware seems to play no role, we could reproduce this on
different
bare metal systems as well as within a qemu based VM.
Since the running program is rather complex, it is not easily possible to carve
out a small reproducer.
We can provide gdb backtraces from freezes inside qemu.
