It has always been our intention to provide a kernel update immediately
post-release to correct this issue.  This new information doesn't change
that plan (and indeed, Dave appears to acknowledge that disabling tcp
timestamping is the lesser evil here).

We should consider re-adding this to the release notes based on this latest
information, so thank you for the pointer.
