Title:
  questing autoinstall crash (on s390x) with daily Sept 10th 2025

Status in Ubuntu on IBM z Systems:
  New
Status in subiquity package in Ubuntu:
  New

Bug description:
  Today I wanted to use the latest questing daily to test an installation with now kernel 6.17 using autoinstall.
  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).
