PNP PS/2 probing racy?

Hi,
I noticed that on one test system of machine when booting the same
kernel I get:
PNP: No PS/2 controller found. Probing ports directly.
serio: i8042 KBD port at 0x60,0x64 irq 1
serio: i8042 AUX port at 0x60,0x64 irq 12
and sometimes on another boot
PNP: PS/2 Controller [PNP0303:PS2K,PNP0f03:PS2M] at 0x60,0x64 irq 1,12
Since I presume the BIOS does not change, is it possible the Linux
procedure for this PNP probe is racy? I haven't checked the code so far.
Full boot logs for both cases:
