A possible cause for this bug has occurred to me, but I wouldn't know where in the kernel code to check for this.
Note: When I talk about a control line, I am using the DTE, i.e computer, end connector reference. In years past there was no standardization for which line on a serial port carried the PPS signal for a GPS and it was a mix of DCD, RTS, and occasionally CTS. Current commercial devices, such as the one I have, seem to mostly use CTS. Is is possible the current kernel code is not looking at ALL those lines for PPS? This would also explain why you have not gotten lots of bug reports as very few people would be running such a device. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1938626 Title: PPS API broken To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1938626/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
