PCI card reader stopped working after upgrading to Ubuntu 14.10

Here's my configuration:

sudo file -s /dev/mmcblk0p1
/dev/mmcblk0p1: DOS/MBR boot sector

Every time I try to mount it manually I get the following:

sudo mount  /dev/mmcblk0p1 /media/vova/
mount: /dev/mmcblk0p1: more filesystems detected. This should not happen,
       use -t <type> to explicitly specify the filesystem type or
       use wipefs(8) to clean up the device.

Can anyone help out? I can't figure this out.
