[Bug 1018241] Re: Kernel panic with ppp and keyspan usa-19hs
Trevor Little, this bug was reported a while ago and there hasn't been
any activity in it recently. We were wondering if this is still an
issue? If so, could you please test for this with the latest development
release of Ubuntu? ISO images are available from
http://cdimage.ubuntu.com/daily-live/current/ .
If it remains an issue, could you please run the following command in
the development release from a Terminal
(Applications->Accessories->Terminal), as it will automatically gather
and attach updated debug information to this report:
apport-collect -p linux REPLACE-WITH-BUG-NUMBER
Please note, given that the information from the prior release is
already available, doing this on a release prior to the development one
would not be helpful.
If reproducible, could you also please test the latest upstream kernel available (not the daily folder) following https://wiki.ubuntu.com/KernelMainlineBuilds ? It will allow additional upstream developers to examine the issue. Once you've tested the upstream kernel, please comment on which kernel version specifically you tested. If this bug is fixed in the mainline kernel, please add the following tags:
kernel-fixed-upstream
kernel-fixed-upstream-VERSION-NUMBER
where VERSION-NUMBER is the version number of the kernel you tested. For example:
kernel-fixed-upstream-v3.13-rc7
This can be done by clicking on the yellow circle with a black pencil icon next to the word Tags located at the bottom of the bug description. As well, please remove the tag:
needs-upstream-testing
If the mainline kernel does not fix this bug, please add the following tags:
kernel-bug-exists-upstream
kernel-bug-exists-upstream-VERSION-NUMBER
As well, please remove the tag:
needs-upstream-testing
Once testing of the upstream kernel is complete, please mark this bug's
Status as Confirmed. Please let us know your results. Thank you for your
understanding.

Title:
Kernel panic with ppp and keyspan usa-19hs
Status in “linux” package in Ubuntu:
Incomplete
Bug description:
I am trying to use Kubuntu 12.04 i386 to connect to an ISP through dial-up.
The ppp module is included in the distribution. I have a Keyspan USA-19HS
USB-to-Serial adapter connected to a US Robotics 56k modem.
The /etc/ppp/options file includes these three options:
demand
persist
idle 60
Ppp connects to the ISP as expected and the remote host can be pinged.
When the connection has been idle for 60 seconds, ppp attempts to
close the USB device /dev/ttyUSB0 and a kernel panic occurs.
Disconnecting the USB device before the timeout occurs causes
pppd to terminate cleanly, but that defeats the "persist" option.
Attached is a screen shot of kernel stack trace.
