Problém s wifi a zvukom - gain calibration timeout

[nosko_]

Zdravím všetkých,

mám následovný problém, ktorý sa tiahne už dlho, a nikdy sa mi ho nechelo vyriešiť, ale kalich mojej trpezlivosti už pretiekol 
Týka sa najskôr wifi(?), a táto chyba následne ovplyvňuje a "kazí" zvuk. Veľmi často sa mi stávalo, že pri prehrávani hudby bol zvuk trhaný, zasekával sa. To isté aj pri filmoch. VLC tento stav nerozdýcha, mplayer zvuk/video prehrá, ale je tam cítiť to sekanie.

Ako je vidieť tento stav trvá vždy pár sekúnd a opakuje sa. O týchto výpisoch viem už dlhú dobu (pár mesiacov), a ako som spomenul, nemal som potrebu ju riešiť, lebo ma nijak neobmedzovala. Jediným problémom bol ten zvuk, ale to som prikladal za chybu zvukovke. Až teraz som zistil, že tieto 2 veci spolu súvisia. A to takto:
- vždy v čase, keď sa vypisujú chyby vyššie, zvuk/video začne sekať.
Tento stav je vidieť aj na obrázku v prílohe? Je vidieť, že v čase keď sa zapisuje do tých logov, systém dačo "robí".

Snažil som sa nájsť riešenie aj na nete, no väčšina príspevkov je z distribúcie "Intrepid" a píšu že táto chyba bude v najbližších distribúciach odstránená, no nejaké konkrétne riešenie tohoto problému som nenašiel. V pár novších príspevkoch bolo spomenuté že táto chyba by už v jadre 2.6.32-22 (moje aktuálne) nemala byť. Prípadne použiť iné ovládače - wireless-linux. (jedno z riešení, ale pre mňa jedno z posledných, nakoľko v karmicu pokiaľ sa pamätám, som takéto problémy nemal).

Mám toshibu, wifi atheros, prípadné výpisy rád poskytnem.
Nestretli ste sa dakto sa dačím podobným?

Ďakujem všetkým za prípadnú pomoc
