Package: linux-image-6.12.73+deb13-amd64
Version: linux-image-6.12.73+deb13-amd64
Severity: normal
Observed on amd64 machines with both Bookworm (6.1.162) and Trixie (6.12.73)
current security linux-image releases. Different CPU familys (Jaguar and
Ryzen). Different chrony versions (4.3-2+deb12u1, 4.6.1-3).
To observe problem, with security kernels installed, setup a PHC clock
source for the existing I210 interface, eg.
refclock PHC /dev/ptp0:extpps
Observe error when starting chrony:
chronyd[837]: Fatal error : Could not enable external PHC timestamping
(wording may be different between the two systems, this was Trixie)
Both work fine under previous kernels 6.1.159 and 6.12.73 (I do not
guarantee there weren't any other versions released between these and the
recent security, neither machine is exposed to the internet and so don't
always get updated immediately.)
In both cases chrony's use of the PHC for timestamping appears unimpaired by
the kernels that fail the PHC refclock. The bookworm platform has linuxptp
installed. phc_ctl and ts2phc work fine with either kernel.
I left the severity at normal, but it's much more serious to a machine
that's syncing to a PPS source like this.
Workaround: roll back those security kernels, of course. And test any future
releases for this issue, of course.
-- System Information:
irrelevant, as I'm reporting from a third machine that has reportbug and
email setup.
