Hi,

For my Debian installation which was in an FCP device is failing to
bootup after upgrading initramfs-tools. Installations in DASD devices
appears to be fine. Looks like the module zfcp was removed in a
particular commit. The zfcp module was not found inside the initramfs
file. This version of initramfs-tools is packages along with trixie. So,
trixie installations will fail on s390x when installed in an FCP device
with this issue.

Thanks,
Pranav
