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.
