I hungrily await said patch, as I believe this is a problem on RM9000
processors as well. I'm seeing "random" SIGILLs on user processes,
particularly large complicated shell scripts like configure on an RM9k
platform.
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)
