I'm using the tx3912 processor for an embedded device and since it doesn't have an fpu, I don't have coprocessor #1. Recently, I remember seeing a fix in process.c for exit_thread and flush_thread, and did apply it - but there still is a problem (at least for me). In traps.c, the save_fp_context and restore_fp_context are set to _save_fp_context (in r2300_fpu.S) which don't check to see if I have a coprocessor available. As I am rather new to the linux/linux-mips development world, I thought I'd give a heads up (it is causing my embedded system to crash). Any direction on fixing it would be welcome, but I'm not sure I'll get to the point where I will submit any patches any time soon. Ryan Martindale QSI Corporation
