UEK can run into the same issue. It is just a picked upstream kernel with a bunch of stuff that Oracle cares about dropped on top of it, and managed by a much smaller team.
Where are you seeing this backported to 5.11 or 2.6.18-404? I'm pretty sure the changeset that introduced the problem
has not been backported to RHEL5 kernels.
Very horribly probably. Though it is a great book, and everyone serious about chess should read it, I think this quote of Anatoly Lein by Jonathan Tisdall in Improve Your Chess Now explains the problem with Kotov best.
"I don't think like a tree - do you think like a tree?"
I believe John Nunn touched on the problems with Kotov's method as well in Secrets of Practical Chess.
The biggest thing to take away from him is the need for a thought process, not necessarily the actual method he describes.
It has no place in air-to-air combat other than trying to not get shot down. It is a dedicated ground attack, CAS platform. It has seen plenty of use in that role in Iraq and Afghanistan. I believe the Soviets in Tom Clancy's Red Storm Rising, and the Taliban both refer to it as the "Devil's Cross".
Probably one of my greatest memories from NTC is being on a hill, and having an A-10 crest the hill, inverted, and then roll over as it continues down the other side on its way to attack a column of OPFOR armor. F-16s and F-18s would just zip right by and be gone in a second. The A-10s would lazily swing back and forth as they worked their way down the valley.
