Description Michael 2013-09-16 10:59:28 UTC

Description of problem:
I have a Clevo laptop with a Realtek 5289 card reader built in, the module 'rtsx_pci_sdmmc' is loaded and _SOME_ SD-cards will automount (although lspci reports "03:00.0 Unassigned class [ff00]: Realtek Semiconductor Co., Ltd. Device 5289 (rev 01)".
Tested SD-cards:
* SDHC  4Gb (Sandisk Ultra II) => OK
* SDHC  8Gb (Sandisk Extreme III) => OK
* SDXC 64Gb (Sandisk Extreme U1 45Mb/s) => FAIL

The latter SDXC card will be detected but mount fails with:
"Error mounting /dev/mmcblk0p1 at /run/media/michael/K-5: Command-line `mount -t "exfat" -o "uhelper=udisks2,nodev,nosuid" "/dev/mmcblk0p1" "/run/media/michael/K-5"' exited with non-zero exit status 32: mount: unknown filesystem type 'exfat'"

Version-Release number of selected component (if applicable):
Linux becksfed 3.10.11-200.fc19.x86_64 #1 SMP Mon Sep 9 13:03:01 UTC 2013 x86_64 x86_64 x86_64 GNU/Linux

How reproducible:
Insert sd-card SDXC 64Gb into Realtek 5289 card reader.

Steps to Reproduce:
1. have a Realtek 5289 card reader, have the module 'rtsx_pci_sdmmc'
2. insert a sd-card SDXC 64Gb into the card reader
3. observe error message upon (auto-) mount

Actual results:
Error mounting /dev/mmcblk0p1 at /run/media/michael/K-5: Command-line `mount -t "exfat" -o "uhelper=udisks2,nodev,nosuid" "/dev/mmcblk0p1" "/run/media/michael/K-5"' exited with non-zero exit status 32: mount: unknown filesystem type 'exfat'

Expected results:
correct mount of SD-card as any other SD-card, e.g. SDHC 8Gb, whatever filesystem is present

Comment 1 Michele Baldessari 2013-09-16 11:32:45 UTC

Hi Michael,

the SDXC card is formatted with 'exfat' which is not yet in any released linux kernel. You can either:
- Try the external inkernel driver: https://github.com/dorimanx/exfat-nofuse
- fuse-exfat

Hope this helps,
Michele

Comment 2 Michael 2013-09-16 11:41:10 UTC

Hey Michele,

thx a lot the hints.
I installed 'fuse-exfat' and the SDXC card is properly mounted.

Should this bug be closed as invalid or set as dependent on exfat integration?

Thx and cheers!
Michael

Comment 3 Michele Baldessari 2013-09-16 11:45:32 UTC

Hi Michael,

feel free to close it, I don't think exfat is yet popular enough to have it in
the default install. Although you could bring this up for discussion on
fedora-devel I guess ;)

regards,
Michele
