@kingbob,

Please try rebooting into the previous kernel to determine if the audio control applet comes back. Also, was the kernel update the only change between boots to cause this issue?

oops, wrong bug, please disregard the last comment.

The running kernel is 2.6.33-999-generic, which is a crack build. These kernels are unsupported and are meant only for testing the very latest linux kernel, which may or may not be in a valid state. As such, I am moving this bug to the 'Invalid' state. If you can reproduce this issue on an Ubuntu kernel, then please post an update, and then you may move the state back to 'New'.

Thanks

Hi,

I can reproduce this on 10.04.01.

$ uname -a
Linux newslut 2.6.32-24-generic #39-Ubuntu SMP Wed Jul 28 05:14:15 UTC 2010 x86_64 GNU/Linux

01:00.0 Ethernet controller: Realtek Semiconductor Co., Ltd. RTL8111/8168B PCI Express Gigabit Ethernet controller (rev 06)

The board is a Gigabyte ga-d525tud.

I see the following messages about 4 or 5 times and then the box will completely hang and need a power cycle to restore it.

kingbob, thank you for reporting this and helping make Ubuntu better. 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, 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 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.
