rtsx_pci_sdmmc: Unable to mount 64Gb SDXC card
Last modified: 2013-09-16 08:15:19 EDT
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)".
* 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
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
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'
correct mount of SD-card as any other SD-card, e.g. SDHC 8Gb, whatever filesystem is present
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
Hope this helps,
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!
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 ;)
