Thank you for opening this bug and helping make Ubuntu better. Your issue seems to be related to this apparmor message:
Jun 18 17:33:33 pscpc kernel: [18794.490995] type=1503 audit(1276878813.771:19): operation="open" pid=2889 parent=1 profile="/usr/sbin/ntpd" requested_mask="rw::" denied_mask="rw::" fsuid=0 ouid=0 name="/dev/ttyS0" So you probably need to edit /etc/apparmor.d/usr.sbin.ntpd to add this capability. Nevertheless, I do agree ntpd should not die a most horrible death because of that. Unfortunately, we do not have a stacktrace to look at. Can you please provide us with one? ** Changed in: ntp (Ubuntu) Importance: Undecided => Low ** Changed in: ntp (Ubuntu) Status: New => Incomplete -- ntpd sementation fault using NMEA driver https://bugs.launchpad.net/bugs/596010 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
