Arch vcerejsi update

Tak jsem si vcera po delsi dobe udelal pacman -Syu a hned mam problem s dvd rom v notasu.
Prace s mechanikou je neunosna.A nejen s ni.
Pokud delam neco s mechanikou je i prace v X prave peklo. Neporadi nekdo jak zapnout DMA u mechaniky kdyz hdparm s libata nefunguje?
Prikladam par vypisu.

prave jsem ted zkousel kernel parametr "combined_mode=ide" ale bez uspechu. Precetl jsem si FAQ na libata strankach a pokusim se jet na ide.
Zajimave je ze to ale predtim na libata behalo bez problemu:/

jeste jsem si ted pohral s mkinitcpio nez zacnu prekompilovavat jadro a svete div se , problem vyresen.
upravil jsem /etc/mkinitcpio.conf a vyhazel nepotrebne veci.
v MODULES mam jen "ide_disk reiserfs"
HOOKS="base udev autodetect ide usbinput keymap filesystems"
udelal "mkinitcpio -p kernel26" a slape to.
sice je ted disk HDA a dvdrom HDC ale to si zvyknu.Hlavne ze uz to slape.
