Do you know more about this? I have a Loongson 3A3000 system that I
have never been able to make stable. I tried pulling patches out of
the glibc, binutils, gcc, and Linux repos I found at but my system still hardlocks,
preventing me from doing much of anything with it.

Do we know why critical looking toolchain patches like "Added misses
sync in mips_process_sync_loop for add sync before ll sc" [0] and "Fix
loads for Loongson3 to promoting stability" [1] have not been
submitted upstream?

I'm interested in supporting Loongson 3 in Gentoo, and the hardware
that has been given to me would be extremely useful for Gentoo's MIPS
port in general, but it's just not usable at all currently.
