Thank you for testing.
Then I have no idea why the kernel hangs...
Random thoughts:
Does it still hang on init=/bin/sh?
Does enabling second and third "#if 0" blocks in arch/mips/mm/fault.c
show some useful information?
Finally, I think there is no serious reason separating c-sb1.c from
c-r4k.c. The c-r4k.c support both vtagged-icache and pindexed-dcache,
therefore SB1 can use it too.
mm/c-r4k.c:probe_pcache()
switch (c->cputype) {
case CPU_20KC:
case CPU_25KF:
case CPU_SB1:
case CPU_SB1A:
c->dcache.flags |= MIPS_CACHE_PINDEX;
case CPU_R10000:
case CPU_R12000:
case CPU_R14000:
break;
kernel/cpu-probe.c:cpu_probe_sibyte()
#if 0
c->options &= ~MIPS_CPU_4K_CACHE;
c->options |= MIPS_CPU_SB1_CACHE;
#endif
