Hi,

I had a short opportunity to boot a SUN x4200 (16GB RAM) with a NetBSD/i386
snapshot (HEAD/200606080000Z/i386/installation/cdrom/boot.iso).
I preferred i386 over amd64 because I thought this would show the fewest
problems...

Issues on this machine:

 Memory:
  Obviously NetBSD did not recognize the whole 16GB RAM:

  WARNING: skipping large memory map entry: 0x100000000/0x300000000/0x1
  ...
  total memory = 3967 MB
  avail memory = 3889 MB

 Clock:
   I do not have the slightest idea what this means:

   RTC BIOS diagnostic error 2

 CPU:
  why does it say "Unknown K7"?

  cpu0: AMD Unknown K7 (Athlon) (686-class), 2393.27 MHz, id 0x20f12

 SAS Adapter (vendor 0x1000 product 0x0050):
  I realize that the LSI Adapter 1064 is not supported by the mpt
  driver and the vendor/product id was missing until yesterday.

 ATI (vendor id 0x1002) and AMD (vendor id 0x1022) devices:
  I do not understand why all those devices are only shown with their
  numerical id. As I just looked them up, all of them were already
  listed in pcidevs, so why does the autoconfiguration say

    ppb0 at pci0 dev 1 function 0: vendor 0x1022 product 0x7450 (rev. 0x13)

  instead of

    ppb0 at pci0 dev 1 function 0: AMD AMD8131 PCI-X Tunnel (rev. 0x13)
  ?

 USB problems:
  A USB keyboard directly attached to the x4200 worked correctly until I
  pulled the plug and got

  : at uhub2 port1 (addr 5) disconnected
  panic: config_detach: forced detach of  failed (45)
  Stopped in pid 4.1 (usb1) at    0xc02d3541:  leave
  ddb>

  An external USB floppy drive from NEC caused a panic when it was
  connected at boot time and disconnected later on:

  uvm_fault (0xc09d8ee9, 0, 1) -> 0xe
  kernel: supervisor trap page fault, code = 0
  Stopped in pid 4.1 (usb1) at 0xc029001f: cmpl $0,0x1c(%ebx)
  ddb>

  I was not able to get a trace because I ran out of time to provoke
  this error again with a serial console. Maybe I can do this sometime
  next week.


  The x4200 machines from SUN have a separate service processor board
  and the machine can be controlled by means of a Java applet from a
  remote system. This applet redirects the remote mouse and keyboard to
  the x4200 where the events appear to originate from a USB mouse and
  keyboard (see "Virtual Keyboard and Mouse" in the kernel output above).
  Even a remote ISO image can be redirected to the x4200 and appears as
  a local CDROM ("Virtual Cdrom Device" above).

  Unfortunately, the virtual keyboard did not work completely. While I
  could type characters, almost every key generated

   uhidev0: bad input length 8 != 0
   uhidev0: bad input length 8 != 0

  This distorted the sysinst screen slightly...
