If, by the Jinke forum you mean the one at jinke.com.cn - No I haven't. I could find no reference there to any of this "New Kernel" stuff and traffic there does seem light to say the least.
I would really need to do some more testing and record the results before firing off a problem report. My comment above was just based on general feelings and the point that the OP did mention "the latest Tirwal firmware" which at the time was 1.9. I see Tirwal has reverted to the "Old Kernel" for his 2.0 offering so perhaps that says something !
