c7e873f85fb60b1af589ac1b0c62353cfe0bbb29 fixed the crash, but not the
failure to read the ROM contents.
So what exactly did ad4a362635353f7ceb66f4038269770fee1025fa change?
A kernel build from ad4a362635353f7ceb66f4038269770fee1025fa plus the fix
c7e873f85fb60b1af589ac1b0c62353cfe0bbb29 gives this in dmesg:

I will see which commit leads to the failure that exists since v3.19-rc4.
