I have a 5.1-current system of Nov 10, also using rev 1.23 of
ata-lowlevel.c.

Without atapicam in the kernel, it boots ok. With atapicam in the
kernel it hangs at the messages (written down from the screen)

(probe2:ata1:0:0:0): Retrying Command
(probe3:ata1:0:1:0): Retrying Command
(probe2:ata2:0:0:0): error 22
(probe4:ata2:0:0:0): Unretryable Error

there are a bunch (15?) more lines like this, and then it just hangs.
