Hi Florian,
Thanks for the patch!
After implementing the patch in our setup we are no longer able to
reproduct the kernel panic.
Unfortunately the server load increases after 5/10 minutes and the logs
are getting spammed with stacktraces.
I included a snippet below.
Do you have any insights on why this happens, and how we can resolve this?
Thanks,
Frank
