I ran into 2 times that my system hung here when booting with a ext4 sd

ext4 as I see it again with a vfat sd card, this morning with Linus'
master branch. Is it a known issue or any idea how to debug this?

Please verify whether the following patch resolves this:

Thanks for your patch! I set up some devices to test reboot this morning
against Linus' master branch. Two devices out of 5, were already hang
for that without your patch, but the other 5 are still work with your
patch.

Will update the result tomorrow morning.

I think your patch solve this. Thanks.
