install hangs on IBM Thinkpad X23

[Dru]

Hello,

I keep running across the same error when installing via floppy for 4.9, 
4.10, and 5.2.1. When the initial kernel loads from mfsroot.flp, it always
hangs solid (requiring a cold boot) at this line:

pci0: <multimedia, audio> at device 31.5 (no driver attached)

I poked around the lists a bit and tried implementing the BIOS IRQ 
settings mentioned in PR 58139 with the same results. Here's the rest of 
what I can see on my screen. The cbb1 message doesn't look friendly:
