2.3.10 is working on the Indy.  I suppose the problem you're observing has
hit me on the Indy when I upgraded it to 2.3.11.  I've traced it to some
inconsistence between the page tables in memory and the TLB which
results in recursive page faults which lockup the process in do_pagefault()
in fault.c.  Really hard to trace and hits both MIPS32 and MIPS64 ...
