Bug#925496: Introduced between v4.18 and v4.19, not fixed in v5.0
I've tested some other kernel versions. In the description below, "fast"
means that the NFS clients booted quickly (~20s) whereas "slow" means that
the NFS clients booted slowly (~100s).
In all cases, rx-usecs=200, rx-frames=4.
Debian versions:
v4.18.0-3-amd64: fast (not tested recently)
v4.19.0-4 (4.19.28-2): slow
Upstream kernel versions built from source:
v4.18.0: fast
v4.18.20: fast
v4.19.31: slow
v5.0.3: slow
I'm bisecting between v4.18 and v4.19 now, but it's slow going.
Mike.
