head -r358132 on Orange Pi+ 2ed: sysctl process stuck at Regulator node lock

[Mark Millard]

I made the mistake of trying "sysctl -a" (piped into grep)
on the serial console. Unfortunately, "sysctl -a" hung up:

# sysctl -a | grep freq
kern.timecounter.tc.ARM MPCore Timecounter.frequency: 24000000
kern.eventtimer.et.ARM MPCore Eventtimer.frequency: 24000000
kern.acct_chkfreq: 15
net.inet.sctp.sack_freq: 2
debug.cpufreq.verbose: 0
debug.cpufreq.lowest: 0
debug.uart_poll_freq: 50
hw.zynq.ddr_pll_frequency: 0
hw.zynq.arm_pll_frequency: 0
hw.zynq.io_pll_frequency: 0
hw.zynq.ps_clk_frequency: 0
load: 2.98  cmd: grep 95554 [piperd] 31.01r 0.03u 0.11s 0% 1896k
^C^C^C
load: 2.81  cmd: sysctl 95553 [Regulator node lock] 69.74r 0.14u 0.47s 0% 2028k
load: 2.26  cmd: sysctl 95553 [Regulator node lock] 157.16r 0.14u 0.47s 0% 2028k

Unfortunately, poudriere is about 20 builds into
building 237 packages.


For reference, from a variant of top:

95553 root         20    0   4760Ki    1888Ki Regula   1   0:01   0.00% sysctl -a



I can still create new ssh sessions and the poudriere
activity seems to have kept going.
