There is currently a thread  on the linux-mips mailing list regarding a bug
in the in-kernel floating point emulator. A proposed patch  is available,
but there are concerns that it may cause problems in an SMP system.
This bug was stumbled across when the "yorick" package was buildd'ed
I'm guessing that this bug is the same one that's causing eglibc to fail
its regression tests. I've got a non-FPU machine running a kernel
with the proposed patch; I can try building eglibc and see if it's
the same problem. It's a slow machine, and I'll have to wait until
I get home to start it up, and it looks like eglibc takes a long time
to compile, so I won't have an immediate answer.
