I have not been running Ubuntu on this machine so can't say if it works
on any earlier version.
I verified that the problem is still there with mainline kernel
v4.9-rc7.
After this problem happens it is not possible to unmount the drive so I
am not able to reboot the machine properly. After a power button forced
reboot running fsck reports errors like this:
fsck från util-linux 2.28.2
** /dev/sdc2

** Checking HFS Plus volume.

volume type is pure HFS+

alternate MDB is at block 0 0x00
primary VHB is at block 2 0x02
alternate VHB is at block 5859651494 0x15d432fa6
sector size = 512 0x200
VolumeObject flags = 0x07
total sectors for volume = 5859651496 0x15d432fa8
total sectors for embedded volume = 0 0x00
Don't know if it's caused by this reported bug or by the power button shutdown.
I repaired the disk with Mac OS disk utility and verified that fsck in
Ubuntu finds it OK again. Then ran the "test" once again. The problem
happened again so crash is not because of existing file system errors.
