Bug Description

I have a Hauppage HVR-2250 DVB card. After upgrading to 10.10, I intermittently get BUG event in the saa7164 driver, and the card stops working. I do not recall this ever happening in 10.04. I will attach the relevant bits of dmesg, and I will try a newer kernel.

Alex Wauk, thank you for reporting this and helping make Ubuntu better. Maverick reached EOL on April 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. Please let us know your results.

Thanks in advance.

First of all, my name is spelled with a C: Wauck.

Secondly, I cancelled my cable subscription and generally stopped caring about TV a while ago, so I haven't been using this card recently. From what I recall, the problem did go away at some point, so I guess I'll just close this bug. If anybody else encounters the same problem, they can create a new bug report.
