  1. Identify SD card reader in IOReg through IOregistryExplorer app (or any equivalent).
  2. Patch the DSDT device under which the SD card reader registers
  3. Remove all instances of VoodooSDHC kext (in SLE and/or LE and/or EFI/CLOVER/kexts folder of EFI partition)
  4. Rebuild cache from Terminal using:
touch -f /S*/L*/E*
touch -f /L*/E*
sudo kextcache -Boot -U /

If you get an error 77, repeat the commands.

Hmmm think I found the problem.  I get this error message when I try to rebuild cache.  

 

rebuilding //System/Library/PrelinkedKernels/prelinkedkernel

kext-dev-mode allowing invalid signature -67062 0xFFFFFFFFFFFEFA0A for kext IOAHCISerialATAPI_Injector.kext

kext-dev-mode allowing invalid signature -67030 0xFFFFFFFFFFFEFA2A for kext AppleHDAIDT.kext

AppleDataSetManagement.kext - dependency for com.apple.iokit.IOAHCIBlockStorage lacks valid OSBundleCompatibleVersion.

AppleDataSetManagement.kext is missing dependencies (including anyway; dependencies may be available from elsewhere)

AppleDataSetManagement.kext - dependency for com.apple.iokit.IOAHCIBlockStorage lacks valid OSBundleCompatibleVersion.

KernelCache ID: (removed my self)

symlink("/System/Library/PrelinkedKernels/prelinkedkernel", "/System/Library/Caches/com.apple.kext.caches/Startup/kernelcache") failed 17 (File exists) <createPrelinkedKernel 2795>

/System/Library/PrelinkedKernels/prelinkedkernel not cached.

Successfully updated disk0s4.

kextcache updated critical boot files, requesting launchd reboot

 

Maybe the IOAHCISerialATAPI kext I placed in /L/E is an old one  and thats why it doesn't work?
