It doesn't need updating, the error you're seeing is:
"DMA: Out of SW-IOMMU space for 65536 bytes at device 0000:09:00.1"
Which I reported upstream here:
http://thread.gmane.org/gmane.linux.kernel.mmc/32629
but which didn't get any answers.
You can test the work-around there though.
Cheers

On my Fedora 22 up to date (kernel 4.0.5-300.fc22.x86_64), when I
insert a SSD card I get this warning:
> giu 30 01:03:27 dodo.home.solinos.it kernel: mmc0: new high speed SDHC card
> at address 59b4
> giu 30 01:03:27 dodo.home.solinos.it kernel: Driver 'mmcblk' needs updating

And after some time (dd if=img of=/dev/mmcblk0) I get many kernel error
like these:

The card written is unusable and I must reboot my notebook to use it
agains.
This problem is new for me (Update from f21 to 22), I have write with
this NB many card SD in the past.
If I usa another notebook with F21 the problem not happens and the card
is written good.
Some one have some suggest?
Many thanks
