I'm also seeing issues in -next which I bisected to this commit, on the
original Raspberry Pi the cpufreq driver fails to come up and I see
(potentially separate?) backtraces:

You can see the report of cpufreq not being loaded in the log.
NFS boots also fail, apparently due to slowness bringing up a Debian
userspace which may well be due to cpufreq isues:
