Never had issues with mine.
But then it might depend on the model and/or the microSD brand.
It is known that with the R4 for DS, some microSDs can cause freezes with some games. Check the list at the bottom of http://wiki.scorpei.com/index.php/R4_compatibility_list
So I guess some similar things can happen on PSP.
