Zamrznutie systemu po zavedeni modulu ath5k

Zdravím,

mám Wi-Fi kartu Topcom Skyr@cer Pro PCI 154 s chipsetom Atheros AR5213 a distribúciu Slackware64 13.1 (kernel 2.6.33.4). Bootovanie sa zastaví po výpise riadkov:

ath5k 0000:04:02.0: PCI INT A -> GSI 18 (level, low) -> IRQ 18
ath5k 0000:04:02.0:registered as 'phy1'

Jadro nereaguje ani na kombinácie CTRL+ALT+SysRq. Jediná možnosť ako nabootovať je pridať modul ath5k do blacklistu. Vyskúšal som latest stable kernel (2.6.35.3) z kernel.org - skopíroval som .config z distribučého jadra a potom 'make oldconfig'. Chyba sa prejavuje stále. Skúšal som aj x86_64 LiveCD Ubuntu 9.04 a openSUSE 11.3 - boot sa zastaví na rovnakých riadkoch.

Mám k dispozícii ešte jeden starší PC (Celeron Tualatin 1GHz) a tam sa chyba neprejavuje (Slackware 13.1 - 2.6.33.4).

Snažil som sa nájsť riešenie na internete, ale v súvislosti s modulom ath5k som narazil väčšinou len na zamrznutie v priebehu činnosti systému, nie pri zavedení modulu. Na nejakom Ubuntu fóre malo zopár ľudí rovnaký problém, ale zjavne riešenie nikto nenašiel.

Chcel by som vás poprosiť, či neviete ako tento problém vyriešiť. Ďakujem
