Then the clock isn't really the problem I suppose. The GPS is reachable and has no offset and low jitter, but doesn't appear to use PPS; although from your boot log it's clear you were apparently expecting to use that. Have you set the flag to use the PPS and does the device deliver (stable) PPS signal? If so, does the device file expected by ntpd exist in your chroot environment (generally a symlink to the real /dev/pps* device) and is it readable by ntpd? Also, if there's an apparmor profile for ntpd, check in /var/log/audit/audit.log (or wherever that is under Fedora, also in the chroot maybe) that apparmor allows the access as well.
