Greetings;
I can't build a bootable 3.12.6 kernel, it seems to die quite fast with a
trace blaming binfmt-some-hex-number. Or fail well into the boot waiting
for / to come available. But if I choose a shell at that failure, it
isn't / that is not shown in a blkid report, it is /boot, named "ububoot"
thats missing. "/", named uburoot, is fine.
Here is blkid output booted to 3.12.0.
gene@coyote:~/src/linux-3.12.6$ blkid

Duplicating this 3.12.0's settings under "filesystems" for 3.12.6 is
apparently not the needed fix.
Clues for the apparently clueless?
Thanks all.
Cheers, Gene

rescue boot it, change the /boot mount line in /etc/fstab to add
noauto (like noauto,defaults...or whatever else you already have) and
change the last column to 0 to disable fsck on it.
It should boot then, and you have the machine fully up were you can do
better debugging.
ie mount /boot may give you a useful error, or it may work...if it
works that implies that in the initrd some piece needed to start /boot
is not there (fs mayb?).
/boot is only needed by the bios...it is not needed when the os is up
except to update teh booting kernel to a new one...

It did not, reports a runaway loop in modprobe binfmt-464c, then spits out
a panic report mentioning the kernel command line option of init= & freezes
with that report still on screen.
In this install, grub does a preliminary modprobe ext2, but the /boot is
ext2-3. And has been for several years.
More clues?
Thanks.

NEW PS: As it turned out, 3.12.0 the version booted as I am working on
this, was not mounting it, so I was writing all my new boot file attempts
to the directory UNDER the mount point. So I changed /etc/fstab to use the
partition LABEL to mount it, and I can mount and umount it at will with no
errors. I've no clue, the UUID looked good, but it obviously wasn't
working, so now my script is trying to write another boot build, about the
20th over the last 2-3 days.
INMNSHO, if it fails to mount /boot as a separate partition, it should stop
and bitch about it in plain English (or whatever the locale setting is at
compile time) right then and there.
How do I go about doing an update to a clone of linux-stable?, I would like
to bisect that in a bit more detail, but linux-stable will not do a git
checkout v3.12.6, I assume because its now 3 or so days old a clone.
Or, should I switch to the Linus tree?
There is also to possibility that my fstab fixes have fixed this, I'll know
in 15 minutes.
Yes, the boot worked this time. I even have audio, but the amp I bought
yesterday needs another 30 db of gain, its just a whisper. Not a linux
problem, it also wasn't very loud when I tested it with a small cd player.
Anyway, thanks for listening/reading this far.
Cheers, Gene
