Lee,
It is good to note that patch45 is delivering the performance
improvements that we intended to deliver.
We are making attempts within TI to enable our customers more on the
GIT tree based development. More concrete steps will follow and I will keep
everyone updated of the same including porting patch 45 to latest DaVinci GIT.
Regards
Swami

Hi
You should have a look on the TI's patch for MVL 2.6.10
I had the same problem on GIt 2.6.23.
Now I'm running MVL 2.6.10 + TI patch level 45 and it rocks!!!
USB performance is VERY good on 'MVL 2.6.10 + TI patch'
I wonder if it is possible to port the TI patch to GIT kernel.
ps. SDHC works perfect on 'MVL 2.6.10 + TI patch' =-)
ps2. Oh, The Link I forgot to mention
http://wiki.davincidsp.com/index.php?title=Linux_patches
refer the bottom side.
Good luck!
