Dotaz: Arch vcerejsi update

[martin]

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.

No asi ti nepomuzu, ale me tohle dela Acer 2413 uz od zacatku, ale jen pri vypalovani, zejmena pri mazani je system naprosto nepouzitelny. Pri beznem cteni je bez problemu.

arch current.

me pri kazde praci s mechanikou :(
zkousel jsem i kernel parametry, nove mkinitcpio a nic.
nejspis nezbyde nic jineho nez prekompilovat kernel bez libata.
nicmene jsem myslel ze to pujde jednoduseji.

[stativ]

Pro libata použij sdparm, balíček je v [core].

[martin]

to bohuzel nevyresi muj problem s hlaskou v dmesg

[kozzi]

Tak nepouzivej libata, ale ide

[martin]

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:/

[kozzi]

A co zkusit downgrade na to starsi jadro.

[martin]

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.
