Hi,

we started observing boot panics with 5.7 on s390x yesterday:

I only released one of the reports to not spam too much but the panics are
still happening with the most recent code.

These panics are NOT present on the current mainline. All other arches are OK.

Given the call trace, I'm guessing it is something related to

https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux-stable-rc.git/commit/?h=linux-5.7.y&id=477d4930b0c7e70c1ac3e3c35e5ad15c5ebde8be
