OT acpi failure

hallo list,

my machine had one of the ahci failures after which it very fast went
stiff (just the caps and num locks did light on/off if appropriate keys
got pressed).  "very fast" means like a half a minute during which i
managed to switch to ttyC0 to see this "one of the ahci failure"
messages that i suspect come from the kernel(?):

$ doas strings /bsd | fgrep ahci | tail -3
%s: ahci_pmp_probe_timeout: failed to clear active cmds: %08x
ahci
%s: ahci_pmp_probe_timeout: ccb in bad state %d

yes, i panicked enough not to take down the message and whether it was
the first or the third one of the three showed above (it definitely read
"ahci0:" at the front of it and "31" at the very end of it) i'm not that
concerned about because the sole question i have to you Gurus is if this
is a dying motherboard or a dying hard disk (the boot one, the other two
are data)

i dare to ask because duckduckgoing from my corner of the web reveals
99% M$ noise with the remaining 1% even more nonsense.

in the meantime i repluged the disk (with the same cable) to another
sata port and i'm hoping to luckily survive till someone knowledgeable
returns with the answer so i know what to mock Mr S.C. for.
