What version of mtd/kernel are you using and on what hardware?

This sounds indeed funny.... almost tragic.
I have seen several minute-long stalls due to either mounting or GC, but all 
processes that are not dependant on that partition keep running nicely.
The only processes that suffer from such a thing are those that want to access 
the partition immediately, so mounting the root partition in rw-mode for 
example, is something to avoid because any given day GC can kick in right 
after mount, and then booting up can take veeery looong.
