Hi,

I have sent this mail before to this mailing list but got no response so
I'm resending it:

I'm not sure if this is the proper way to report bugs, I will gladly
report it bugzilla if that is preferred.

I have been experiencing an issue with the rtsx_pci driver.
I cannot read SDHC or SDXC cards. I'm running linux 3.9.9 on a x86_64.
Normal SD cards seems to work fine.

This is the output from lspci -vvv:

When I insert a SDHC card I get the following messages in dmesg:

[ 2078.383348] mmc0: cannot verify signal voltage switch

the device is created but I have trouble reading from it,
I ran dd if=/dev/mmcblk0 of=/dev/null bs=4K count=100 and it is very slow:

100+0 records in
100+0 records out
409600 bytes (410 kB) copied, 70.098 s, 5.8 kB/s

and dmesg outputs:

If I run mkfs.vfat /dev/mmcblk0 it outputs:

mkfs.fat 3.0.20 (12 Jun 2013)
mkfs.vfat: failed whilst writing FAT

and the dmesg gives:
