boot/i386/pc/startup_raw.S:115: Error: attempt to move .org backwards

I'm getting this error trying to compile grub2 from bzr. The bzr pull

Try increasing
#define GRUB_KERNEL_I386_PC_NO_REED_SOLOMON_PART 0x6e0
in include/grub/offsets.h, but keep it divisible by 8 and don't increase
too much.

Vladimir,

I increased from 0x6e0 to 0x7f0 (the smallest that works) so it
compiled without any problem. Booted and it's stuck at the very first
grub notification "grub ...".

Make sure that you don't try to use old grub-setup with new images or
vice-versa. Also another possible trouble is gcc adding unexpected
sections. Can you submit your lzma_decompress.image?

In particular running grub-install from build directory w/o make install
will attempt to use outdated utils.

It's a full install. "make" followed by "make install".

Your lzma_decompress.image is fine (as in: I added it into my build
system and then resulting grub-mkrescue image still works fine. I will
need your diskboot.img, boot.img lzma_decompress.img, core.img and
kernel.img.

Can't find the "core.img" file. The rest of the files are attached.

core.img is in /boot/grub. I still was unable to reproduce. All of the
files you sent are fine. Are you sure that your grub-mkimage and
grub-setup were updated?
Do you have an x86-64 or i386 system?

Vladimir,

It's x86-64 and grub-mkimage and grub-setup are updated as well.

Something changed after Nov 14. I can compile the same source from
download prior to Nov 14, and it works fine. Same compiler, same
kernel, same environment. And I checked COMMAND_LINE_SIZE and on
linux-3.x, it's not limited to 256 anymore.

I use this to run grub.


 # grub-install --force --no-floppy --boot-directory=/boot /dev/sda

Thanks,
Jeff

Vladimir,

Just removed and do a clean download from
http://bzr.savannah.gnu.org/r/grub/trunk/grub and run autogen.sh and
configure and ended up getting stuck at "Loading GRUB".

Tried "grub-emu" and it runs fine, but on "real" pc, it doesn't run.

If I replace the whole grub-core directory with those from Nov 14, it
works ok, and I see quite a few changes in there after Nov 14.

Thanks,
Jeff

Does it work in qemu? (sudo qemu /dev/sda, be sure not to launch the OS

Done all that, in fact, using "root" and not sudo.

"qemu /dev/sda" ... same issue, stuck in ... (at least this is better
than reboot the real PC).

Booting from Hard Disk...
GRUB loading.

Again, installing from Nov 14 src and "qemu /dev/sda" works.

Which exact revision does it refer to? Did you try r3607? The only

I just tried compiling and runing it on 32-bit and it's working. Looks
like it's a 64-bit problem only.  Same kernel version, gcc, glibc ...
but 32-bit only.

It doesn't make any sense since there files modified since Nov 14 are
always compiled as 32-bit

It's strange, but anyway I'll try to bisect it down. I don't know bzr
that well so learning as I go along.

Vladimir, the source that works for is at rev 3586.

I checked further. When I ran the compiled 64-bit grub-install on an
SD card, the SD booted fine. The same grub-install doesn't work my
/dev/sda.

I zeroed into this problem and it's repeatable. It's the partition
table. Works fine except when the disk partition contains 2 or more
physical partitions and an extended partitions.

Use fdisk to create the following partitions:

I zeroed into this problem and it's repeatable. It's the partition
table + reiserfs. Works fine except when the disk partition contains 2 or more
physical partitions and an extended partitions.

Use fdisk to create the following partitions:

1) create physical partition 1. 10MB
2) create physical partition 2. 10MB
3) create extended partition using the remaining space
4) create logical partition 5 using the remaining space
5) mkreiserfs on partition 5, mount and grub2 on it
6) reboot and it hangs


Works if:
1) Partition 1 removed or
2) use non-reiserfs for partition 5

Here's my partitions ...

Disk /dev/sda: 274.9 GB, 274877906944 bytes
   Device Boot      Start         End      Blocks   Id  System
/dev/sda1            2048       22527       10240   83  Linux
/dev/sda2           22528       43007       10240   83  Linux
/dev/sda3           43008   536870911   268413952    5  Extended
/dev/sda5           45056   536870911   268412928   83  Linux

That's pretty weird since no recent changes to reiserfs or msdos part 
but I can attempt to recreate. Could you perhaps try to bisect to get 
exact faulting revision? Your range spans 20 intensive commits. 
Bisecting it is at most 5 attempts but will simplify the debugging greately.

I bisect it down further. Still workd at rev 3588. Couldn't compile
3589. Doesn't work at rev 3590.

It seems even on 32-bit, it's not 100% reliable. Works 99% of the
time, but hangs occasionally when I copy a new boot file to the
reiserfs partition.

Thanks. It should help although I'm still scratching my head on this one.

What do you mean by "copying boot file"?

Hello. I've discovered and fixed a floating bug with symptoms matching

Is it "GRUB" or "GRUB Loading"?
