>Description:
When building one of the above mentioned kernels with current sources and
then trying to netboot it the following (or something similar) happenes:

Sun Ultra 1 UPA/SBus (UltraSPARC 167MHz), No Keyboard
OpenBoot 3.11, 96 MB memory installed, Serial #7964830.
Ethernet address 8:0:20:79:88:9e, Host ID: 8079889e.



Boot device: net  File and args:                                      
14c00 >> NetBSD/sparc64 OpenFirmware Boot, Revision 
>How-To-Repeat:
Make a 32bit sparc64-kernel with sparc (32bit) userland and try to boot it
on an Ultra1.

 Sometimes it doesn't get to the debugger and this happens:

 BTW: Please note in the bootmessage that the reported cache sizes are completely
 wrong. I send in a PR on this (with fix) on 5th March (PR #12844).
 
 The last working kernel I have is dated June 20.
