[Bug 39553] kernel panic at boot, 64-bit version

[Teo]

Public bug reported:

Flight 6: I tested both live and install versions. The result is the
same - kernel panic while booting. I took a picture, but don't know how
to attach it, so I will type it down.

I am not sure, but is it possible that mmcfg is related to multimedia?
If so, while installing Breeze on same machine I had to disable sound in
BIOS and blacklist snd_hda_init. Thought it might help knowing this.
