Hello Robert,
I've also noticed that after setup_install when I umount /mnt file
system again I endup with one CPU being 100% in sys.
hsfs`hs_freenode+0x74
hsfs`hsfs_inactive+0xa4
genunix`dnlc_purge_vfsp+0x19c
genunix`dounmount+0x10
genunix`umount2+0x140
unix`syscall_trap32+0xcc
Looks like this is what is causing it.
