Hello all,
   I've been playing around NetBSD on my HC-4600 for a little while now
off and on, and I've ran into a few problem. I'm wondering if anyone can
point me to any other information, code sections, or suggestions on
fixing these problem. I've tried goggling some answers but I've come up
a little short on some of the information.

   Some of these problems seem to be related to differences between the
HC-4100/HC-4500 and the HC-4600. The HC-4600 physically has a PR31700 in
it like the HC-4100 and HC-4500 but it uses the TX3912 kernel like
stated on the ports page. The generic kernel hard locks the machine.
- From looking around there isn't much info on the HC-4600 and NetBSD.
Most people seem to have used the HC-4100/HC-4500.

I do program in C (among other languages) and have a some kernel
experience, just not with NetBSD directly. So I'm not bad with technical
details.

1) The HC-4600 is running CE 2.0 (Never got in on the free 2.11 upgrade
   they had going for a while) but the pbsdboot.exe crashes, but
   pbsdboot1.exe seems to work fine. The pbsdboot.exe crashes with a:

      Fatal Application Error

      Application PBSDBOOT.EXE has performed an illegal operation and
      will be shut down. If the problems persists, contact the program
      vendor.	
		
      Program: PBSDBOOT.EXE
      Exception: 0xc0000005
      Address: 01fed124
		
2) 1gb PNY CF card doesn't work, but my 64mb Lexar and 32mb PNY do.
   After some googling it it sounds like the same problems that the
   hpcarm people were having a near the beginning of the year. Something
   about the CF speed-up code in the wd.c.

3) Suspend works but fine but it doesn't turn off the lcd back light and
   the light key doesn't seem to be mapped or doesn't function. Maybe
   another HC-4500 and HC4600 difference.

4) The 'p' key seems not to be mapped. I get a 'hpckbd: unknown scan
   code 0x3b (7, 3)' printed twice each time i hit the 'p' key. I've
   looked at the hpckbdkeymap.h and it looks trivial to add. This might
   be something with the difference between the keyboards for the
   models.

I've tries and recreated these problems under NetBSD 2.1 and the most
recent 3.0 RC6 release.
