I downloaded the Vogue kernel, dated 3-8-10, from here:
I just want to report that I am occasionally getting sdcard errors but then the Android has no issues retrieving information from the sdcard. Someone else reported the same issue. I can't find the particular thread now, I'm hoping it was in this thread. I just wanted to report; me too. Is there anything you want to look at when it happens again?
I will probably roll back to the previous kernel. I will say that this kernel does seem to do a lot better on battery life but then it has been a lite day on phone usage.
