Not being too familiar with s390, I can't guess at what went wrong here. It doesn't look like a kernel bug per se, but rather something wrong with the initramfs. Can you boot the old kernel and unpack the initramfs to see if the needed modules got added? See the DEBUG section of initramfs-tools(8) for a command to do the unpacking. > Here is the boot log: > > ---------- > > Booting default (debian)... > [ 0.000000] Initializing cgroup subsys cpuset > [ 0.000000] Initializing cgroup subsys cpu > [ 0.000000] Linux version 2.6.26-2-s390 (Debian 2.6.26-15) > (da...@debian.org) (gcc version 4.1.3 20080704 (prerelease) (Debian > 4.1.2-25)) #1 SMP Fri Mar 27 03:31:55 UTC 2009 > [ 0.000000] We are running under VM (31 bit mode) > [ 0.000000] This machine has an IEEE fpu > [ 0.000000] Zone PFN ranges: > [ 0.000000] Normal 0 -> 131072 > [ 0.000000] Movable zone start PFN for each node > [ 0.000000] early_node_map[1] active PFN ranges > [ 0.000000] 0: 0 -> 131071 > [ 0.000000] Built 1 zonelists in Zone order, mobility grouping on.
