Hi,

Hope you are doing well!

Quick update from our side: The reproducers from the previous email
still trigger the WARNING on v5.15 (commit hash
3a5928702e7120f83f703fd566082bfb59f1a57e). Happy to also test on
other kernel versions if that helps.

Please let us know if there is any other helpful information we can provide.

Wishing you a nice day!

Best,
Marius
