[Bug 2146873] Re: Try default 26.04/s390x installation on z/VM using DASD

[Frank Heimes]

Hi Thorsten,
thanks for the explanation on the above fdasd message.

After I got a hint from Olivier about using the 26.04 installer with a 25.10 image,
I tried to recreate the situation on our z13.
I did several different installation that all worked,
but when I moved over to custom installation, and when I selected to format ext4 there I face a crash.
(Was not obvious that it happens with custom installations only.)

I'm attaching the full /var/crash and /var/log and a txt file with my
reproducing steps as tgz here for further analysis.
