Not one I have seen on similar (but not identical) models.

Have you done a verbose boot to confirm the place it hangs? Frequently
the problem is with something that happens just after the last printed
item comes out and verbose boot logs will often show that.

Both the memory card slot and the Bluetooth are almost certainly
connected to the USB, not directly to the PCI, so I tend to suspect
USB (or USB related) issues, in which case this is hte wrong list. Of
course, I certainly might be wrong.
