 This:
 
   wdc0:0:0: lost interrupt
   type: ata tc_bcount: 512 tc_skip: 0
 
 probably indicates that something is not right when netbsd tries to
 talk to the card.
 
 I'm not familiar with this hardware or wdc(4) internals.  One thing
 that you can try _easily_ is using older NetBSD releases.  You don't
 have to bother with the installation, just drop an old kernel to the
 CF card under a different name and try to boot it.  Some wd/wdc
 changes might have broken the driver for hpcarm b/c it, obviously,
 doesn't get a lot of testing there...
 
 The next thing to try (if none of the old kernels work) would be using
 an older, simpler CF card.  I don't know _anything_ about the
 hardware, but HPC is _old_ and who knows what corners they cut.
 E.g. you can't use large cards (a 8GB CF card doesn't work in my
 Jornada 690) b/c some address lines are not there or something.  I did
 run into cards that just didn't work in my hpcsh, though it's been
 decades ago and I don't remember any details.
