I've seen the same thing but on a different processor (VR5432). gcc 3.0.1, glibc 2.2.3. I suspect stack/register corruption. Regards, Brad ----- Original Message ----- From: Green To: Linux-mips ; MipsMailList Sent: Sunday, November 04, 2001 10:43 PM Subject: do_ri( ) Dear all, I often get into trouble executing multithread application. Sometimes it will appear the message " Illegal instruction = 0xXXXX " in do_ri() function in /arch/mips/kernel/traps.c. It happened randomly. Up to now, I still didn't know how to fix bug. If any one know how to fix it, please reply me. Appreciate in sincerely. P.S My mips bos is R3912. ~~ Green greeen@iii.org.tw
