This was more or less exactly what I was seeing on an O2 RM7000 setup until the
fix for errata #28 was put in (which should already be enabled for RM9000 systems).
Check include/asm-mips/war.h and make sure your machine is included in the list
that define ICACHE_REFILLS_WORKAROUND_WAR. If not, add it and test; and fire
off a patch. Should fix that issue (especially if bash is the only userland
process dying while complex g++ compiles behave fine)
