Probably problem is in umockdev.  Build fails with segmentation fault in test-umockdev-vala:
do_page_fault() command='test-umockdev-v' type=15 address=0x00000010 in libumockdev.so.0.3.0[26167,f8e82000+37000]
trap #15: Data TLB miss fault, vm_start = 0x00010000, vm_end = 0x00025000
command line: /home/dave/debian/umockdev/umockdev-0.18.4/obj-hppa-linux-gnu/test-umockdev-vala

Looks like a NULL pointer issue.

I tried duplicating this manually but I haven't been able to duplicate segmentation fault.  Sixth test aborts
trying to open /dev/tty:

All other umockdev tests seem to run okay with my manual setup.
