[hardy] traceback when plugging in usb-audio device

[Martin Pool]

Binary package hint: linux-source-2.6.22

I just plugged a Logitech usb headset (model A-0205A) into my hardy machine and got this traceback

[Leann Ogasawara (leannogasawara)]

Hi Martin,

This report was filed against the Gutsty 2.6.22 kernel but from your comment and the stack trace output it seems you are indeed running Hardy 2.6.24. I'm changing the source package name over to 'linux' which is the Hardy kernel source package (the naming convention changed from linux-source-2.6.xx to just linux at the beginning of Hardy). If you can, could you verify if this is still an issue on the latest 2.6.24-11 kernel? If so, care to attach the full dmesg output which captures the error messages. Thanks!

[Leann Ogasawara (leannogasawara)]

The Ubuntu Kernel Team is planning to move to the 2.6.27 kernel for the upcoming Intrepid Ibex 8.10 release. As a result, the kernel team would appreciate it if you could please test this newer 2.6.27 Ubuntu kernel. There are one of two ways you should be able to test:

1) If you are comfortable installing packages on your own, the linux-image-2.6.27-* package is currently available for you to install and test.

--or--

2) The upcoming Alpha5 for Intrepid Ibex 8.10 will contain this newer 2.6.27 Ubuntu kernel. Alpha5 is set to be released Thursday Sept 4. Please watch http://www.ubuntu.com/testing for Alpha5 to be announced. You should then be able to test via a LiveCD.

Please let us know immediately if this newer 2.6.27 kernel resolves the bug reported here or if the issue remains. More importantly, please open a new bug report for each new bug/regression introduced by the 2.6.27 kernel and tag the bug report with 'linux-2.6.27'. Also, please specifically note if the issue does or does not appear in the 2.6.26 kernel. Thanks again, we really appreicate your help and feedback.

This was still a problem when I tried it about a month ago on hardy.
I've recently upgraded that machine to intrepid and will try to
re-test.

working ok for me in 2.6.27-3-generic

[C Filorux (breakfast)]

By way of confirmation, I'm running 2.6.24-19-generic. While playing sound through the headset, I bumped the connector, and got the crash below - this is unusual on my system. The device is .. Bus 004 Device 007: ID 046d:0a0c Logitech, Inc. dmesg says this - from when I originally plugged it in (time+1021), to when I bumped it (time+2176), to when I plugged it in again (in a different slot) (time+2184).:

This is consistently ok for me in intrepid.

[Leann Ogasawara (leannogasawara)]

Since Martin is the original bug reporter, I'm marking this "Fix Released" for Intrepid. Thanks.
