The problem here is that del_gendisk, syncs the device.
This is new change, made after you did your drivers.

I have this problem on jMicron too (which otherwise works fine).


PS:

I have a copy of your ms_block.c.
I would would be very happy if you share with me, what problems does it
still have (besides need of trivial port for changes in block system,
because I want to push it upstream too.

I have MS DUO 64M to test it against.
