Hi all,

On Linux Mint Debian Edition, my sd card reader controller does not appear to be functioning nor present after i wake up my laptop from suspend mode. This is quite irritating. I've searched and tried several methods to make it work to no avail.

Here is the output of lspci before doing a suspend:

And here it is after I woken up the computer from suspend mode:

It is these three lines that are missing:
02:00.0 System peripheral: JMicron Technology Corp. SD/MMC Host Controller
02:00.2 SD Host controller: JMicron Technology Corp. Standard SD Host Controller
02:00.3 System peripheral: JMicron Technology Corp. MS Host Controller

The SDcard in the SD card slot is no longer mounted of course, and the device on /dev/mmcblk0p1 is no longer there.

These are the steps that I have tried (I tried every step independently):

• STEP 1: I edited the file pm-suspend
  /usr/sbin/pm-suspend
  Edited the fist line which is not bashed (#), which is:
  export STASHNAME=pm-suspend
  before that line, I added
  umount /dev/mmcblk*
  This just managed to unmount the sd card before suspending but the problem of the controller disappearing prevailed.
  
  I tried also:
  In: etc/pm/sleep.d
  I created 010_unmount_SD.sh with the following content:
  
  
  

  # Drop to: /etc/pm/sleep.d
  # Use this script to prevent data loss on mounted MMC/SD
  # cards. It syncs data and umounts all mmcblk devices prior to
  # suspend, and cancels suspend if umounting was not possible
  # (i.e: something locks a file)
  touch /home/me/Desktop/suspended.txt;
  case "${1}" in
      hibernate|suspend)
          /bin/sync
          for drive in $( /bin/ls /dev/mmcblk?p* ); do
              /bin/umount ${drive} > /dev/null
              # If umount failed: abort suspend
              if [ $? -gt 0 ]; then
              # Test if device keeps mounted. Previous command could fail
              # (i.e device was not mounted) with a non-stopper
              # problem for the suspend process.
              /bin/mount | /bin/grep ${drive}
              if [ $? -eq 0 ]; then
                  exit 1
              fi
              fi
          done
          ;;
  #    resume|thaw)

  This also just managed to unmount the sd card before suspending but the problem of the controller disappearing prevailed.
  
  
• STEP 2: I added the following line to the file /etc/pm/config.d/00sleep_module to unload the module before standby:
  SUSPEND_MODULES="$SUSPEND_MODULES sdhci"
  
  I don't have an idea or the knowledge to see if this actually executes. All I can see is that the problem persists. That is, of the controller disappearing on wake up prevailed.
  
  I also tried another syntax:
  SUSPEND_MODULES="sdhci sdhci_pci"
  Same result here.
  
  
• STEP 3: I tried removing the modules by hand before suspend
  sudo rmmod -v sdhci
  sudo rmmod -v sdhci_pci
  sudo rmmod -v mmc_block
  
  Suspended the system. On wake-up the controller didn't show up on lspci.
  
  Tryed to readd them by doing:
  sudo modprobe -v sdhci
  sudo modprobe -v sdhci_pci
  sudo modprobe -v mmc_block
  
  The system didn't complain when re-adding the modules but the sd card controller still did not show

So here I am now. Kind of out of options. I'd be happy to provide some logs if needed. I'd appreciate any help I can get.
The problem for me lies in the fact that this tiny Dell has only a 16Gb SSD which basically requires some kind extra storage. That's where the SDcard comes in for me. I'm thankful for any kind of assistance.

PS: This is what happens when the controller is actually working and when an sd card is inserted:
