So they're not quite gone yet, just a whole lot less frequent. have fun Michael

I cvs updated, built a new kernel and saw problems again. Older kernel ( sources from just after this commit) is ok. No clue why, I'll keep digging, might be local crap or PEBCAK. Also, what I've been messing with is both kernel and userland built as n32, guess I should try o32 too. With n32 I get the same compiler problems as on Loongson - SIGBUS from gmp whenever optimization is enabled. One built without .asm routines in gmp seems to work so far ( managed to build a working tcsh ) There's a possibly related issue on Loongson - nfs writes get corrupted in much the same way. No such problem with the working kernel on the O2 though. have fun Michael
