Those results were generated by editing the grub kernel command line on-the-fly at boot time. As you say, the probe bitmask does not show up. If I add it to the YAST boot loader it does show up but there is an error message. For example: [ 6.515532] snd_hda_intel: `' invalid for parameter `probe_mask' The file with the 0x101 bitmask is attached. Should I generate the results for 0x102 - 0x180 despite the error?
