>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?)

 Sysinst does not do any magic to detect disks, it relies on the kernel for
 that, so in this case: sysctkl hw.disknames

 It certainly should not segfault, but that is slightly tricky to debug in
 install environments.

 Let's fix the disk issue first: does the kernel recognize any disks?

 Yes, it reports the CF card as detected on boot. Removing & re-attaching
 the CF card detaches & re-attaches wdc(4) & wd(4).

 No error messages during attach?
 What happens if you re-attach while in the first sysinst menu and then
 try to install?

 same thing, reports that it can't find any disk.
 Just to clarify, I was able to perform an install using sysinst from a
 release I built earlier last month. current working kernel reports being
 built on the 19th, now I can't remember if I ran update before baking
 the release on the 19th or the checkout was a couple of days older. I've
 gone through all the commits since those dates but nothing shines out
 though there are numerous changes to VFS & filesystem which is within
 the same ball park as the issue but no idea to rule out a suspect.

 I was wrong - apparently I did not commit the sysctl hw.disknames change
 yet :-/

 Can you check the /dev/*wd* entries and compare with a working system?

 So basically no differences.

 Please go to the Utility Menu, run /bin/sh and manually try to access
 the disk, like just display the disklabel.

 But you said it did attach? No error messages during attach?

 OK, so can you show

 sysctl kern.rawpartition

 please?

 unfortunately, sysctl command is not on the hpcarm miniroot.fs

 Try the manual disklabel with a full path, like:

  disklabel /dev/rwd0d

 (your /dev/ assumes it would be rwd0c, just making sure it did not 
 accidentialy change in kernel w/o updating userland)

 Possibly incorrect major number for /dev/wd0* and /dev/rwd0* ?

 That worked.
 I have a partition c & d (fstype unused)

 So some commit changed hpcarm to use MBR common code (or something like
 that). We need to find out if this was by accident and revert, or fix
 all the loose ends (easy, now that it is analyzed).

 Thinking back now, I was installing builds natively on the Jornada but
 got fed up with the time it was taking so I switched to installing from
 sysinst on i386.

 Could it be it that?

 To rule this out, I wiped the CF with dd if=/dev/zero of=/dev/disk2
 bs=1m count=1 and recreated a mbr partition on the CF spanning the disk,
 formatted fat.

 I copied hpcboot, netbsd-JORNADA720.gz & miniroot.fs to the CF card &
 tried to install again.

 sysinst still reports no disk can be found.

 disklabel wd0 reports
 wd0: no disk label

 disklabel /dev/rwd0d works & reports a d & e partition exist.

 This almost sounds like you've got a file named wd0 sitting in your 
 working directory.  Older versions of getdiskrawname(3) would find that 
 file rather than looking in /dev ...
