Zdravim, pouzivam opensuse 10.2, pri niektorych nabootovaniach (nie pri kazdom) mam problem robit akukolvek akciu s cdromkou, zrejme v suvislosti s (vypis prikazu ps):
USER PID %CPU %MEM VSZ RSS TTY STAT START TIME COMMAND
root 3155 0.0 0.1 8080 704 ? D 11:23 0:00 hald-addon-storage: polling /dev/hdc
Nejaky dalsi prikaz napr. mount /dev/hdc takisto zamrzne so statusom D. Zrejme je potrebne nastavit PIO/DMA rezimy. V biose mam obe nastavene na 'auto'.
Nevie niekto poradit ako to riesit? Vdaka.
problem s cd/dvdrom

otazka je aka je to vobec doska, verzia jadra - moze byt ze sa nepohodol ovladac radica diskov s cdrom, alebo kabel -moze byt ze je zle zasunuty (datovy aj napajaci), popripade ci vobec stiha zdroj.
vypisy hdparm -i /dev/cdrom z obidvoch verzii distribucie si mohol dat uz davno, alebo si aspon pozriet aky je tam rozdiel a v com.
inac kedze je to notebook tak by som sa ani nedivil keby mal nie priliz kompatibilnu verziu biosu s linuxom alebo ak by sa s tebou ta mechanika pomaly lucila a balila si kable na cestu do kremikoveho neba. skus sa priznat ako dlho nosis ten notebook a kolko krat si v mechanike pocas prenosu zabudol medium. a kolko krat si s nim buchol o zem alebo o nejaky roh ... to vsetko skodi mechanickym castiam ...
mne zvykla odist mechanika na NB za cca pol roka (o kvalite HW pomlcim). najprv mala problem s nejakymi mediami, potom obcas po sebe neprecitala vypalene data alebo to po nej neprecitala ina mechanika. az mi na koniec zamavala :-) samozrejme ze robila aj ine psie kusy, ale aspon mi s tymi mechanikami bolo veselo ...

teda tych default 16-bit sa mi zda divnych, na dsktope mam na odoch cdrom nastavene 32-bit
v biose som nastavil PIO=0, DMA=UDMA2.
Do adresara /etc/init.d/rc5.d som pridal subor s nazvom S99dma a obsahom:
#!/bin/bash
#
#nastavenie DMA na /dev/hdc
#
/sbin/hdparm -d1 /dev/hdc
#koniec
Uz by ma len zaujimalo, ci je to korektne riesenie, a ci z toho nemam ocakavat nejake ine problemy. Dik za rady.

Jan 17 10:42:08 linux-v5ny kernel: hdc: drive_cmd: error=0x04 { AbortedCommand }
este vypis z dmesg | grep hdc:

Takze sa mi to nezda moc ok, ale hdparm/dev/hdc ako aj mount /dev/hdc idu ok. Neviete co znamenaju tie chybove hlasenia a prip ako to riesit? Inac take sa objavolali sem tam aj v suse 10.1, myslim po tom co sa prepol rezim DMA na PIO. Vdaka.
