> Except that OPAL/petitboot cannot boot a zImage ... FAIL !~ Epic fail. Really sorry about that (and the effort involved). Apologies, everyone.

Problem: ------------ In the current situation, some issues occur because of 1) or 2): 1) the presence of /boot/vmlinu*x* w/ no debug symbols (vmlinux conventionally contains debug symbols) - systemtap's search path includes it first, and assumes it has debug symbols, and thus fail on probes involving the "kernel" identifier - perf had a similar issue on trusty IIRC, which required specifying /proc/kallsyms by hand (it seems automatic on utopic) 2) the lack of /boot/vmlinu*z* - kdump-config (from makedumpfile): only tests for existence of /boot/vmlinu*z* .. and potentially others. I believe the limiting factors that kept us using vmlinu*x* was either 1) yaboot, or 2) lack of zImage support for 64el on kernel. Neither should be a problem anymore: for 1) ppc64el uses grub only, and for 2) 3.16 contains the zImage-support patchset. Solution Proposal: ------------------------- I had success in building, booting and installing utopic w/ vmlinuz. Attaching the (trivial) patches for the kernel (ubuntu-utopic.git, master branch) and debian-installer (src pkg). The install w/ mini.iso finished successfully. Although it ended up installing vmlinux (it download linux-image from Canonical, I guess), it was just a matter of installing the patched linux-image package to get vmlinuz installed and booted successfully. If there's no objection/more fixes to do, I'd submit the kernel patch on the kernel-team mailing list, and check what's needed to get this back on trusty (zImage support has 16 patches IIRC).
