>Description:
The INSTALL_JORNADA720 kernel and miniroot.fs in snapshots for this week (maybe a little earlier too, since last week) have been having various issues.
If the root file system is mountable, sysinst is unable to perform an install because it reports no hard disk can detected.
If you try to partition a disk from the utility menu, sysinst seg faults.

looking at the core file generated (sysinst doesn't contain symbols) issuing a backtrace reports
backtrace stopped: previous frame identical to this frame (corrupt stack?)

>How-To-Repeat:
try to use hpcarm/installation/netbsd-JORNADA720.gz & hpcarm/installation/miniroot/miniroot.fs.gz from a recent snapshot in head
