When I boot without the initrd, it hangs after "unable to open an initial console". I figured that, at this point in boot, it hasn't mounted my root, it doesn't have devfs, so it needs a /dev in a initrd. At least this way I got further in the boot. I just verified again that without the RAM fs it can't find an initial console. > If that's a initrd image built for a generic kernel (as it seems) it won't > work - initrd images contains kernel modules, which are kernel version > specific. Per above, I was just trying to get init/main.c a /dev that it could use to open the console. I was going to fix the modules once I got that far. > > checking if image is initramfs... it is > > Ok, this is known not to work in UML. <sigh> OK, now I know.

I agree, the kitchen sink is probably in there somewhere. But I'd spent several days trying to get a kernel with what I considered a reasonable config to boot, so in desperation I decided to duplicate what someone else had posted as working. > It's in SKAS0 mode, so you debug it like SKAS3: > > gdb ./vmlinux > (gdb) run ubd0=.........
