Raul, did you try with (eg) Karmic ? I have a 2540p on order and my

until this issue is resolved. Thats a different mix than your test of
using 2.6.31 on Lucid.

The steps to take now are:
1. Test the current Lucid proposed kernel. There isn't anything new in
that kernel likely to fix this, but we need to test for completion.
2. Cherry pick the patch above into that kernel, and test again.
The current Lucid proposed kernel is available from:
This patch is also one that needs testing for bug 561802. If anyone
