Dotaz: DVD - existuje, po vložení DVD žádná reakce

[Milan]

Ahoj, mám nainstalované GENTOO, jádro 2.6.31-r6. už jsem zkoušel snad vše, ale stále mi nefunguje CD/DVD mechanika. Po vložení CD/DVD disku chvíli chroupe ale není žádná odezva systému. Nejde ani moutnout ručně. S jiným systémem funguje.
výpis z dmesg:
--------------

No a co za chybu to vypíše?

mount xyz abc ?

Máte v jádře přeloženou podporu toho FS který je na tom CD/DVD?

[Milan]

po
mount -t iso9660 /dev/sr0 /mnt/

mount: v /dev/sr0 nenalezeno žádné médium

mechanika funguje, nabootuju z ní bez problémů.

Tuhle hlášku jsem z nepochopitelných důvodů dostal, když uživatel neměl právo komunikovat s mechanikou. Prožeňte příkaz mount přes nástroj strace, ať vidíme, kde přesně to selže. Pokud mountujete jako běžný uživatel, jste ve skupině cdrom? Jak se chová cdrecord -atip na CD-R/RW médiu? Protože jste psal, že se v jiných systémech (distribucích Linuxu?) a při bootování (tedy i když jede Linux a čte souborový systém z média) funguje, viděl bych to na nějakou chybu konfigurace.

mount dělám pod rootem
