Package: linux-image-5.18.0-0.bpo.1-arm64
Version: 5.18.2-1~bpo11+1
Severity: normal
Dear Maintainer,
today I briefly tried the backport 5.18 kernel on bullseye. It boots fine,
but as soon as some network traffic happens, it panics with a backtrace
indicating some kind of problem in the dpaa2_eth netwokr driver.
The problem can be reproduced 100% within very few seconds after system boot. One can
usually still ssh into the machine, but then the first shell command producing
more than a single-line output (like ls -l /etc) makes the kernel panic like below.
As soon as I downgraded back to linux-image-5.10.0-15-arm64 = 5.10.120-1 the problem
disappeared. On 5.10.120-1 the network runs very stable.
