Folks...
I'm experiencing some instability on recent sgimips kernels, and the
problem seems to be in generic MIPS code.
I'm getting traps with a panic/traceback like the following while
building the NetBSD source tree (src and objects on NFS).
sq0: receive FIFO overflow
panic: lockmgr: no context
Stopped at netbsd:cpu_Debugger+0x4: jr ra
