I order get all the efforts spent to pay off and to let others for benefit from
what we have learned so far, I would like to find a fix for this issue. For
this I need more stuff:
1. add drm.debug=0x4 to the kernel command line, reboot and run as root:
   # dmesg > dmesg.out
   Please get me the content of 'dmesg.out'.
2. run as root:
   # intel_bios_dumper  intel_bios.data
   get me the output file 'intel_bios.data'
