Bug Description

Binary package hint: evince

 have installed Ubuntu 10.10 RC1 64 bit version on my laptop (Acer 5520) and I have connected Winfast DTV Dongle. It was ok as in Lucid.

Hi Vladimir,

If you could also please test the latest upstream kernel available that would be great. It will allow additional upstream developers to examine the issue. Refer to https://wiki.ubuntu.com/KernelMainlineBuilds . Once you've tested the upstream kernel, please remove the 'needs-upstream-testing' tag. This can be done by clicking on the yellow pencil icon next to the tag located at the bottom of the bug description and deleting the 'needs-upstream-testing' text. Please let us know your results.

Thanks in advance.

hi again,
I just tested some of the mainlain kernels; here's what I found out:

v2.6.32.24.10-lucid: no crash
v2.6.33.1-lucid/: CRASH!

everything after v2.6.33.1-lucid/ gets me the same crash and everything before v2.6.32.24.10-lucid works.
so the regression obviouly happend between v2.6.32.24.10-lucid and v2.6.33.1-lucid

I hope you are able to find whats wrong now ...

No idea. As a temporary fix, try rebuilding the kernel as shown at

https://patchwork.kernel.org/patch/101784/

This works for me, and does not seem to have any side effects, but you
need to rebuild every time you update the kernel.

Vladimir, thank you for reporting this and helping make Ubuntu better. Maverick reached EOL on April 10, 2012.
Please see this document for currently supported Ubuntu releases:
https://wiki.ubuntu.com/Releases

We were wondering if this is still an issue in a supported release? If so, can you try with the latest development release of Ubuntu? ISO CD images are available from http://cdimage.ubuntu.com/releases/ .

If it remains an issue, could you run the following command in a supported release from a Terminal (Applications->Accessories->Terminal). It will automatically gather and attach updated debug information to this report.

apport-collect -p linux <replace-with-bug-number>

Also, if you could test the latest upstream kernel available that would be great. It will allow additional upstream developers to examine the issue. Refer to https://wiki.ubuntu.com/KernelMainlineBuilds . Once you've tested the upstream kernel, please remove the 'needs-upstream-testing' tag. This can be done by clicking on the yellow pencil icon next to the tag located at the bottom of the bug description and deleting the 'needs-upstream-testing' text.

If this bug is fixed in the mainline kernel, please add the following tag 'kernel-fixed-upstream'.

If the mainline kernel does not fix this bug, please add the tag: 'kernel-bug-exists-upstream'.

If you are unable to test the mainline kernel, for example it will not boot, please add the tag: 'kernel-unable-to-test-upstream'.

Please let us know your results. Thanks in advance.
