that's worked fine until now, but with this kernel tree, if i do the
above and reboot, i not only can't stop in GRUB, but the boot fails as
the kernel panics, claiming it can't mount a root file system.
i recovered by booting off the CD into rescue mode, mounting
/dev/sda1 (/boot), then literally editing grub/grub.cfg and deleting
the entries for that new kernel. nothing else would allow me to boot.
If GRUB doesn't work with the entries for your self-built kernel but
does without them, it seems that exactly these entries makes GRUB choke.
WAG: Does it get better if you rename your kernel and initrd files to
something that doesn't end with a '+' character?
i'm testing that right now, but an earlier example worked just fine
and, in fact, the stock kernel build process explicitly appends a "+"
in certain cases.
anyway, i just built a 2.6.35-rc4 kernel, about to install, create
initramfs, update grub and reboot. stay tuned ...
