[ImoLUG] cdrom o sda?

[Mr. Franco Tampieri]

Mumble sembra proprio un problema di bus, anche perchè hdparm è inutilizzato
(tutte le op sono commentate)
però ho trovato una seri di topic interessanti:

http://forums.gentoo.org/viewtopic-t-615665-highlight-driveready+seekcomplete+datarequest.html
http://forums.gentoo.org/viewtopic-t-615773.html

Ne risullta che è una impostazione del kernel... un problema di gestione di
irq sul bus...

Dacci una occhiatina :)

Cheers

Franco
