radeondrmfb issue causes boot to hang on Macbook Pro

[eovnu87435ds]

Hi everybody. I am trying to install Kali on my Macbook Pro 8,2 (Early 2011) and am having some issues doing so. I can successfully work through the Kali Graphical Installer, install Grub EFI on my EFI partition, and begin to boot, but the boot process hangs at this line:

fb: conflicting fb hw usage radeondrmfb vs EFI VGA - removing generic driver.

This guide outlines what I have done to get as far as I did: https://top-hat-sec.com/forum/index....31815#msg31815

Here is my partition map(I am booted into OS X from an external HDD, so the output is diskutility. disk0sX is the equivalent of /dev/sdaX):

   #:                       TYPE NAME                    SIZE       IDENTIFIER
   0:      GUID_partition_scheme                        *750.2 GB   disk0
   1:                        EFI EFI                      398.5 MB   disk0s1
   2:       Microsoft Basic Data Kali Linux                20.0 GB    disk0s2
   3:                 Linux Swap                          4.0 GB     disk0s3

And here is my grub.cfg:

About 30 seconds into the boot process is where it hangs, leaving the line above as the last output.
I tried to fix it by booting into the live CD, chrooting to the install partition, and blacklisting radeondrmfb using the method shown here for debian installs, but it still hangs at the same point: https://wiki.debian.org/KernelModuleBlacklisting

Any help would be greatly appreciated.

Hi

I have the same problem. I could circumvent this by adding the following kernel parameters to it. This will allow booting. But once booted I can not seem to get Xorg running
