There is likely something fishy in the syscall interception path from
arch/mips/kernel/entry.S; all the syscalls seem to return error values
mistakenly once the pipelining is in effect. You may want to check your
changes in this area.

Btw, it would be nice to work in an open manner and post your code on
this list if you want to ask for help about it here. Contribution has to
work both ways. TIA,
