Here's some more information.

Using the same disc image, but with an older version of qemu, the guest 
Linux boots:

...
umount[11]: Unimplemented SPARC system call 188
cat[12]: Unimplemented SPARC system call 188
SCSI subsystem driver Revision: 1.00
esp0: IRQ 36 SCSI ID 7 Clk 40MHz CCYC=25000 CCF=8 TOut 167 NCR53C90(esp100)
ESP: Total of 1 ESP hosts found, 1 actually in use.

Partition check:

Compare this with the looping version in git:
>>> ....
>>> initrd-tools: 0.1.84.2
>>> umount[11]: Unimplemented SPARC system call 188
>>> cat[12]: Unimplemented SPARC system call 188
>>>
>>> Then qemu loops.
Perhaps the problem lies within the SCSI emulation?
