The fix made in this bug broke production systems for me. Same symptom as in comment #4. Which bug is tracking the regression? Meanwhile, I downgrade kernel. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1397976 Title: tty hangup regression in 3.13 kernel (trusty LTS) To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1397976/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
[Bug 1397976] Re: tty hangup regression in 3.13 kernel (trusty LTS)
Yep, me too, about 10 production systems broke because of that regression. I had to push a special kernel on our own PPA to fix it :-/ Well, now there is a new kernel in -proposed with the additional patch that fix that regression. That's probably the easiest now: just add the -proposed repository temporarily to the package sources, and update the kernel. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1397976 Title: tty hangup regression in 3.13 kernel (trusty LTS) To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1397976/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

As described in comment #4, the regression that the 'fix' introduced is still present in 3.13.0-65.105~precise1.

[Bug 1397976] Re: tty hangup regression in 3.13 kernel (trusty LTS)
Hi,
I've just got the new -proposed kernel with that fix, and got an important
regression: it broke tty connection to my devices using FTDI chips.
I haven't fully checked yet, but I think that's because you've cherry-
picked commit eafbe67f84761d787802e5113d895a316b6292fe "n_tty: Refactor
input_available_p() by call site", without also taking commit
a5934804a834f525c9e6289935ceef65b952b101 "n_tty: Fix poll() when
TIME_CHAR and MIN_CHAR == 0" (which fixes that first commit).
Note: I'm not affected by the original bug, so cannot comment on the
effect of the other commits.
How to reproduce the regression:
? python
> import serial
> p = serial.Serial("/dev/ttyACM0", timeout=1)
> p.read()
SerialException: device reports readiness to read but returned no data (device
disconnected?)
Expected:
p.read() waits one second and returns nothing (due to timeout).

This bug is awaiting verification that the kernel in -proposed solves the problem. Please test the kernel and update this bug with the results. If the problem is solved, change the tag 'verification-needed- trusty' to 'verification-done-trusty'. If verification is not done by 5 working days from today, this fix will be dropped from the source code, and this bug will be closed. See https://wiki.ubuntu.com/Testing/EnableProposed for documentation how to enable and use -proposed.
