Could be that CloneZilla is writing a corrupted partition table. I have
only ever seen this issue in cases where people were using CloneZilla.

You can just backport this patch that upstream has to workaround this
problem [1]. Basically, they just changed the order in which partitions
are probed and thus, parted probes for MS-DOS first, then later for
Atari.

I hope I'll find some time in the near future to properly investigate
this issue though. The idea is to have a look at how the kernel does
the Atari partition probing, the code there seems more reliable.

Thanks,
Adrian
