This bug is awaiting verification that the kernel for Natty and Lucid in -proposed solves the problem (2.6.32-41.89, 2.6.38-15.59). Please test the kernel and update this bug with the results. If the problem is solved, change the tag 'verification-needed-<releasename>' to 'verification-done-<releasename>'.

If verification is not done by one week from today, this fix will be dropped from the source code, and this bug will be closed.

See https://wiki.ubuntu.com/Testing/EnableProposed for documentation how to enable and use -proposed. Thank you!

From the build logs, this issue seems to be sorted out both on natty and on lucid. Here's the link to the old build logs, containing the warning:

- Lucid: https://launchpadlibrarian.net/98910046/buildlog_ubuntu-lucid-i386.linux_2.6.32-41.88_BUILDING.txt.gz
- Natty: https://launchpadlibrarian.net/98586259/buildlog_ubuntu-natty-i386.linux_2.6.38-14.58_BUILDING.txt.gz

And the link to the latest build logs, without the warning:

- Lucid: https://launchpadlibrarian.net/103608120/buildlog_ubuntu-lucid-sparc.linux_2.6.32-41.89_BUILDING.txt.gz
- Natty: https://launchpadlibrarian.net/103291509/buildlog_ubuntu-natty-i386.linux_2.6.38-15.59_BUILDING.txt.gz

So, tagging the bug verified for both series.
