nasty bug in /usr/sbin/grub-probe
I am not so sure about this yet until I can rebuild the required grub
binaries with full debug info. For at least a year ( or more ) I have
seen "really bad things"(tm) happen when I try to make a new initrd on
sparc64. Generally the machine seems to pack up and go away with nary a
single packet out to the world. To look into this problem I use a serial
attached good old 9600 baud console and watch what happens when I try to
do a make install from within the Linux source tree :

[grub-probe:47798]
So then. That is what I call "really bad". There is nothing I can do
other than to fire a BREAK over the serial lines to the console and drop
the machine to firmware prompt. Nasty.
Once the machine gathers its wits and stands up once again with a
running situation I dig into what is really going on. We have a nifty
script called /usr/sbin/grub-mkconfig that does a whack of stuff but
certainly it runs /usr/sbin/grub-probe very early and gathers some
information therein.
We see these lines :
# Device containing our userland. Typically used for root= parameter.
GRUB_DEVICE="`${grub_probe} --target=device /`"
GRUB_DEVICE_UUID="`${grub_probe} --device ${GRUB_DEVICE}
--target=fs_uuid 2> /dev/null`" || true
GRUB_DEVICE_PARTUUID="`${grub_probe} --device ${GRUB_DEVICE}
--target=partuuid 2> /dev/null`" || true
Well at the very least we can run /usr/sbin/grub-probe with command line
parameters "--target=device /" :
oot@hades:~# TERM=dumb LC_ALL=C /usr/bin/gdb -q /usr/sbin/grub-probe

OKay that works. Yes /dev/sda4 seems correct. I see :
root@hades:~# df -h

udev 485M 0 485M 0% /dev
tmpfs 100M 752K 99M 1% /run

/dev/sda6 15G 2.9G 12G 20% /usr/local
root@hades:~#
The next line in the script /usr/sbin/grub-mkconfig fires off this :
# /usr/sbin/grub-probe --device /dev/sda4 --target=fs_uuid
The machine never recovers from that. Very bad things happen.
To demonstrate :

So therefore I think that there is a bug in /usr/sbin/grub-probe and it
really kills the whole "make install" process from within the Linux
kernel source tree or any other way you choose to run it.
Has anyone else seen this ?
