BTW; the ubuntu bug also has one report without "P" taint flag --- but OTOH tainted "M"... https://bugs.launchpad.net/ubuntu/+source/linux/+bug/317227/comments/3
This appears to be an old bug - please try 2.6.29
(In reply to comment #2) > This appears to be an old bug Is it a bug filed in the kernel.org bugzilla? If so, which one? I'd like to direct my vendor (Ubuntu) to including the patch for it in their distribution. > please try 2.6.29 My vendor (Ubuntu) is not at 2.6.29 yet. I don't really have the time to maintain my own kernel, which is why I use a distro. :-/
A whole collection of reports like that one were sorted with changes in 2.6.28/9 so unless you can verify the problem still exists in 2.6.29 I'm afraid your bug report isn't very useful.
Brian, you can try these: https://wiki.ubuntu.com/KernelMainlineBuilds http://ubuntuforums.org/archive/index.php/t-1108281.html
