Pinged mei folks, waiting for reply
Martin, dis you made kernel bug for this? I guess we could drop CFL from this as CFL-S2 is now CFL-S3 and no issues seen there.
Also reported on kernel.org: https://bugzilla.kernel.org/show_bug.cgi?id=199541
According to the kernel bug, there is a patch that fixes the issue when applied to our CI. If the patch is not yet merged in any of the kernels we use and we can't close the bug, we could at least reduce the priority. This bug is currently at the top of the list of our overdue bugs, but it doesn't look like there is much we can do.
