Please test the last 2.6.30.y from kernel.org. If the bug is still there, test
2.6.31-rc4 or later. If the bug is still there, please report it here or at
bugzilla.kernel.org.

If the bug is not present in 2.6.30.y, try to find the commit that fixed it
(using git-bisect, but marking good commits as 'bad' and bad commits as 'good')
and point the Fedora kernel maintainer(s) to it. Same for 2.6.31-rc4 or later.

Best,
Rafael

Thank you for your reply. I have now installed kernel
2.6.31-0.94.rc4.fc12.x86_64 from Fedora development. If the problem
continues I will report it.

Thanks,

Lee.
