IIRC, it's my slightly-dramatized rendering of what one of the ALSA
developers said when he responded to my bug report about not being able
to record from the mic input on my Intel chipset. He basically said that
the ALSA driver was not being notified *by the kernel* that the audio
input buffer was full and ready to be read. He advised me to try again
with a more recent kernel. Now the part about the kernel people blaming
it on ALSA developers may have come from this list.

But all that was a couple of years ago. I've not taken the time to try
recording via the laptop mic, because I'm planning to equip one of my
desk systems (with much more disk space and a real sound card!) to serve
that function.
