Summary: sometimes sdio mmc device node can not generated correctly after partition
Details:
After partition, sometimes mmc device node can not generated correctly in bf518f-ezbrd/bf548-ezkit in trunk and 2010 branch.
Bellow is the log:
--
fdisk /dev/mmcblk0
The number of cylinders for this disk is set to 31000.
There is nothing wrong with that, but this is larger than 1024,
and could in certain setups cause problems with:
1) software that runs at boot time (e.g., old versions of LILO)
2) booting and partitioning software from other OSs
(e.g., DOS FDISK, OS/2 FDISK)

Follow-ups

It is somewhat similar to bug 5806. I've updated sdiommc test script to make
sure that device nodes have enough time to be created. Need to recheck the
result for some time later.
--- Vivi Li 2010-11-10 01:35:01
This bug still exists after my modification to test script.

can't reproduce

Can not see this bug in latest trunk.
Close it.
