	Nejaky mene testovaci RELEASE by tam nesel ?

	Jedna z moznych teorii totiz je, ze jde o nekompatibility ovladace s 
konkretnim hardwarem. U znackovych pocitacu a tedy i HP je sice 
automaticky kandidatem customizovany hardware, ale u 5.3R nelze vyloucit 
ani vadu ovladacu.

	Druhym favoritem je syntakticka nebo i obsahova vada v ACPI tabulkach. 
Oboji neni vubec nic neobvykleho. TO lze otestovat spustenim systemu bez 
ACPI.

	Tady ale ma kazda sitovka a radic vlastni preruseni ...

	Nicmene, zpet k veci - ztraty IRQ mohou vest, v lepsim pripade, ke 
ztrate vykonu v horsim i k nefunkcnosti. Pokud by slo o sitovku, muze 
dopady vice-mene eliminovat POLLING  mod (nevim, jestli ho xl umi).
