Package: linux-image-2.6.26-2-s390 Version: 2.6.26-15 Severity: critical This particular Linux kernel image will not boot on a virtual machine in ESA mode under z/VM. I have not tried other platforms (LPAR, for example).
Here is the boot log: ---------- Booting default (debian)...

Begin: Loading essential drivers ... ---------- at which point the modules listed in /etc/initramfs-tools/modules are loaded. In my case, these modules are dasd_diag_mod dasd_eckd_mod dasd_mod vmcp loop Without the dasd modules, the permanent root file system cannot be mounted. I tried re-running update-initramfs for this specific kernel version, but it made no difference.
