SD Card not detected after hibernate.
 
I'm on Slackware 14.1 (default kernel 3.10.17-smp). My SD Host controller is:
Code:
03:01.1 SD Host controller: Ricoh Co Ltd R5C822 SD/SDIO/MMC/MS/MSPro Host Adapter (rev 19)
Whenever I resume from the hibernate state (suspend to disk) I'm experiencing an issue related to my sdcard reader:
the insertion of the SD Card is not detected after the hibernation/resume cycle.
Instead, no issue with (suspend to ram)/resume cycle.

After resume, whenever I insert the sdcard into the slot, I can't get any message in /var/log/messages, too.

I've also tried to reload the following kernel modules, but unfortunately no success! :(
Code:
mmc_core, mmc_block, sdhci, sdhci_pci, b44, ssb.
Please, is there any workaround I could try? It'd be fine, if I could avoid to reboot!

Just one question: was there a card in the reader (at the time of suspend/hibernation)?

No, it wasn't.

According to you suggestion, I've made a try by taking the following steps:
1. Reboot.
2. Insert the sd card into the card reader.
  1. the devices "/dev/mmcblk0" and "/dev/mmcblk0p1" have been correctly created.
  2. /var/log/messages correctly returns:
    Code:
    May 19 09:53:14 darkstar kernel: [  202.087779] mmc0: new high speed SDHC card at address 1234
    May 19 09:53:14 darkstar kernel: [  202.110985] mmcblk0: mmc0:1234 SA08G 7.41 GiB (ro)
    May 19 09:53:14 darkstar kernel: [  202.113193]  mmcblk0: p1
3. Hibernate the system with the card still into the slot and with the two existing nodes (mmcblk0 and mmcblk0p1) in /dev.
4. At the next resume, the same issue unfortunately occurs again: the card isn't detected, no more mmcblk0 and mmcblk0p1 in /dev and no output in /var/log/message. :(

Solved!
 
I want to resume this old thread just to mark it as solved because I finally could mount sd-cards again after hibernate!
Still on slackware 14.1, kernel 3.10.103-smp, removing and reloading the sdhci_pci kernel module solves the issue!
Code:
rmmod sdhci-pci
modprobe sdhci-pci
I hope it can be useful to someone else! :)

I had the same issue (same SD Host controller, same Slackware version, same result) and your solution worked. So yes, it was useful to someone!
Thank you very much!
