[Bug 2122581] [NEW] questing autoinstall crash (on s390x) with daily Sept 10th 2025

[Frank Heimes]

Public bug reported:

Today I wanted to use the latest questing daily to test an installation with now kernel 6.17.
There is no up-to-date daily in current (probably for a reason), hence I used pending.
Trying to autoinstall on LPAR or on z/VM led to a crash.

I'm attaching the two sets of logs (hwe0003 is z/VM, s1lp15 is LPAR).
