I have a device with two separate PPS time sources wired up to two of the Software Defined Pins on
an Intel i211 NIC (ala https://blog.dan.drown.org/apu2-ntp-server-2/). This works great with chrony
4.0 (and even better in 4.3, thanks!) on Linux 5.10.
However, I just tried to upgrade to 6.1 and the second PPS went silent. The testptp utility in the
kernel tree shows the first pin working fine, but when I hook the fourth pin up to channel two (as
chrony does as well), I get radio silence.
