I see your point. I'll merge them into my repo with Baikal-T1 CSP/BSP patches and will deliver all at once when the kernel is ready to accept the changes (most likely in 3 - 5 months). @Jiaxun, if you've any hardware which for sure supports the strong UC ordering, feel free to submit a patchset which activates the proposed here config together with my STRONG_UC_ORDERING-alteration applied before your changes. -Sergey > > Thomas. > > -- > Crap can work.
