Comment 12 for bug 155702

Dear Henrik,
I have just read the criteria for stable release updates (SRU) - one of them is "Bugs which represent severe regressions from the previous release of Ubuntu".
To use UDMA66 when UDMA100 is available might not be a serious regression. A 300% boot (and _resume_) time increase would be judged a serious regression by any user, tough.

Furthermore the logic behind the SRU-guidelines is to not risk any system instability. "Therefore, when updates are proposed, they must be accompanied by a strong rationale and present a low risk of regressions." The fact that the proposed patch (which does only weigh 6 chars) went into other major distributions as well as into mainline kernel shows quite clearly, that it fullfills both points: A neglectable risk of regressions _and_ a strong enough rational to convince a number of knowledgeable kernel and distribution maintainers.

So please do ignore all that talk about reenabling the old pata-code. That's clearly outside of the scope of a SRU. Fixing libata's pata_sis is (in my opinion) not.
