[Anatoly Pugachev]

Hello!

I can't make sun partition table with parted over existing one on
debian sparc64 physical machine Sun SPARC T5120:

You found a bug in GNU Parted! Here's what you have to do:


Assertion (bios_geom->cylinders == (PedSector) (dev->length /
cyl_size)) at ../../../libparted/labels/sun.c:190 in function
sun_alloc() failed.

Aborted



PS: OS is Linux debian sid/unstable (kernel 4.5 , glibc 2.22) sparc64.

Well emacs is good. Except for the missing text editor. xD

I don't have commit access to qemu. I think meanwhile it's more or
less centralized and pretty much everything is committed by Peter
Maydell.

The way to get the patches  is to post them on the Mailing list CCing
the sub-system maintainer.
According to the current MAINTAINERS file (I'm not loud, the actual
file name is all caps), M68K
has "Orphan" status. Which probably mean that you gonna have to CC
Peter himself.

Perhaps you would like to be a m68k mainainer? You cope with
debian-sparc very well. :-)

Well, for my part, I think that emacs is much better than vim! xD

Btw, from your above comment it sounds like you have commit
access to qemu? Am I understanding this correctly? Because
I have a few qemu patches for the m68k target which are still
waiting to be merged.
