Ahoj, deje se mi zajimava vec, pokud mam pripojenou dvd mechaniku (sata - stejne jako vsechny disky), tak se PC zpomali a dost, nebot kazdou chvilku blika disk jak silenej. Zjistil jsem, ze to mozna souvisi s IRQ 19 :) Pokud se podivam do dmesg, vidim, ze mi kernel pise, abych zkusim nabootovat s option irqpool. Nicmene jsem torchu googlil a ve vetsine pripadu tato option zpusobi problemy s eth, atd. Nemate nekdo s tim zkusenost? V HW se tolk nevyznam.... Hazim sem vypis /proc/intrerrups a dmesg. Budu rad za kazdou radu. Nevim, jestli neni bug nahodou primo v kernelu
