I have similar problems on my IP22 Indy with R4000/100MHz.
Also refer to my thread from last November:
  http://mail-index.netbsd.org/port-sgimips/2004/11/11/0000.html

Which CPU revision do you have? I have V2.2. There is an Errata
from MIPS about the R4000 2.2 and 3.0, which describes 55(!)
CPU bugs and their workarounds. Most prominently, the "branch
to end of page" hardware bug, which has no workaround in NetBSD.

The errata is available at:
  http://www.mips.com/content/PressRoom/TechLibrary/RSeriesDocs/content_html
and is called: R4000PC/SC Errata, Processor Revision 2.2 and 3.0.
