Though I don't use Ubuntu, I've been hit by the same issue. Luckily the redhat bug report (https://bugzilla.redhat.com/show_bug.cgi?id=573201) contains a link to the kernel fix.
Kernel fix is here: http://git.kernel.org/?p=linux/kernel/git/davem/net-2.6.git;a=commitdiff;h=78f1cd02457252e1ffbc6caa44a17424a45286b8
The fix is not in -stable yet.
