I have this same problem under 2.2.17pre4 -- the sound card makes
hideous noises the first time it's used with the same error messages.
it started happening only when i started building IDE as a module and
booting with an initrd.
Do you have ide-* modularized? I see you say you have a "Dell
Laptop"... mine is also, a Latitude CS. Which model do you have?
In Documentation/sound/NM256, it mentions that some Sony laptops need
a 'buffertop' option to stop "random noise"... does anyone have any
idea how to locate the optimum value for this option?
