Thanks to Dimitri for pointing out that the comment #2 is not designed to actually SET the HW Clock from the host, but to ALLOW the HW Clock to be set with /sbin/hwclock. I had completely missed this.
Next step is to try the sequence described in comment #2 (on the BMC and also on the host), and then retry using /sbin/hwclock on the host to change the HW clock time. ** Changed in: ubuntu-power-systems Status: Triaged => In Progress -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1837443 Title: [Power9][Witherspoon dd2.3] unable to set hwclock To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu-power-systems/+bug/1837443/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
