Hi Krampus,
The reason i thought it might be your firmware was because i had a similar issue with a build that would get hanged at the same message, and doing the firmware update fixed it.
[Linux-EFI, setup=0x10cd, size=0x1de2d0]
[Initrd, addr=0xd895000, size=0x2a91b5]
In your case, since the stock Linux image boot just fine, it doesn't look like a firmware issue.
