Right, I had DEBUG_INFO set. Stupid me. Now it looks much better: valdese:~/soft/linux/kernel-git> ls -lh arch/alpha/boot/vmlinux* -rwxr-xr-x 1 ut ut 6.4M Sep 21 18:12 arch/alpha/boot/vmlinux* -rw-r--r-- 1 ut ut 3.0M Sep 21 18:12 arch/alpha/boot/vmlinux.gz But it still dies before the first message from the kernel shows up.

I'm sure that other Alpha configurations are still working, but the Jensen is a bit special. So far I know it's the only Alpha which needs aboot and not milo as second stage bootloader. aboot itself seems to be OK, as I can boot the ancient kernel just fine, but when I'm trying to boot other kernels, I'm coming as far as: aboot: loading compressed vmlinux-5-15-rc2 and that's it. I don't think I have to do something special with the compressed image and according to https://tldp.org/HOWTO/SRM-HOWTO/aboot.html I don't have to. But why do I have the feeling I am doing something fundamentally wrong? Was there something with a different kernel jumping in point or a special build option? I remember something like that, but can't grasp it nor find it on the web. I would try the SRM bootimage (make bootimage), but the build is broken: valdese:~/soft/linux/kernel-git> make -j8 ARCH=alpha CROSS_COMPILE=alpha-linux- bootimage ...
