A similar patch for EXCP_AdEL seems to fix the problems
with Linux floating point emulation.
Linux uses self modifying code on the stack in the FPU emulation
and terminates this code using "lwzero,1(zero)"
(which raises EXCP_AdEL).
Sometimes, a system call which follows and is also on the sta

I ha
It seems there is an issue with the translation block flushing when
writing to the code regions in the MIPS full system emulation. Using a
2.6 kernel which is basically running in single user mode, I use an
extremely simple program:
main () {
int i;
for (i = 0; i < 10; i++) {
p
