Comment 22 for bug 395403

From these last few comments, it appears to be a hardware problem. Try 9.10 as below and if it occurs, try disabliing devs per #21. If it works, note the IRQ etc. and let us know.

Can you confirm this issue exists with the most recent Karmic Koala 9.10 Beta release? ISO CD images are available at http://cdimage.ubuntu.com/releases/karmic/ . If the issue remains with Karmic it would be great to then also test the latest upstream mainline kernel available. This will allow additional upstream developers to examine this issue. Refer to https://wiki.ubuntu.com/KernelMainlineBuilds . Thanks in advance.
