Bug#931500:
Same picture with different NFS minor versions - 4.0, 4.1
Same picture with and without hyperthreading
Same picture with and without different mitigations on/off via kernel
command line.
100% reproducible within 4-5 repeats of make -j `cat /proc/cpuinfo |
grep processor | wc -l` ; make clean on an openwrt tree. Reproducing it
on a linux tree takes a bit longer, but it is also reproducible - 10-12
times.
So actually the executive summary is - NFS is broken. Completely. That
is not level 6 bug, that is a much higher, please adjust priority
accordingly.
