Yes, that sounds like a filesystem failed while holding locks. > 3- This laptop experienced 2 long stalls (20~25 sec) during boot, > apparently after scanning usb_storage devices and starting portmap.

Please test the next Linus git tree (2.6.15-git7) and see if we've propagated it into there too. There's not much point in fiddling with -mm2. If git7 is OK then please test the next -mm and if it still fails then yes, doing a bisection would really help.
