OK; I rebooted the new(er) laptop with the previous kernel (that was
built with "option DIAGNOSTIC") and reproduced the issue:

--- albert.catwhisker.org ping statistics ---
37 packets transmitted, 37 packets received, 0.0% packet loss
round-trip min/avg/max/stddev = 0.451/13.832/178.867/41.904 ms

Then:

g1-216(13.0-C)[2] sudo sysctl debug.vmem_check
Password:
debug.vmem_check: 1
g1-216(13.0-C)[3] sudo sysctl debug.vmem_check=0
debug.vmem_check: 1 -> 0

On recheck:

--- albert.catwhisker.org ping statistics ---
60 packets transmitted, 60 packets received, 0.0% packet loss
round-trip min/avg/max/stddev = 0.411/0.551/1.051/0.084 ms

which looks pretty good to me.

Thank you, Konstantin! :-)

Peace,
david

There's no point in asking Trump "Sir, have you no decency?" -- it is
already well established that neither he nor his enablers have any.
