15" Mbpro Retina (10,1) hangs at startuproutine at -pci pause:sdxc
I have this problem with my MacBookPro 15": MacBook Pro Retina Mid 2012 (MacBookPro10,1 NVIDIA GPU)
I bought this MBPro used over eBay and after I got it the seller checked it again and told me it was defect with a black screen.
He brought it to repair in germany and a new mainboard was installed - the MBPro run ok with OSX 10.8 as far I noticed.
Mbpro Serialno: c02jl4qcdkq2
New mainpport part: MLB,2.6GHZ,IVB 4C-GT2,8GB 1333MHZ DDR3 (G170799072)
After I upgraded to 10.9 (and 10.9.5 later) and installing my system from a timemachine backup I now have the same pci pause: sdxc error :-(
On power on or a reboot the macbook hangs with the spinning wheel.
In Verbose mode I see that the last entry is pci pause: sdxcI can wait for long minutes (around10) and then the macbook boots into desktop.
What I did already:
Long Hardware Test - no errors
Reinstall 10.8. and 10.9. - problem still there
Repair volume and userrights with discinstall - problem still there
This hanging is really annoying and I like to know what I can do.
