kernel 2.6 --> no cdrom

Hello,

i've updated my kernel, so i've 2.6 know runnig. Installation of the ati-drivers runs smooth.

Now I just wanted to mount my cdrom... it'gone.

It can't find it in /dev/cdrom or /dev/ide or something like that.

It is listed under /proc/ide as hdc but not in /dev....

And in dmesg it is also listed:

------------
ICH4: chipset revision 1
ICH4: not 100% native mode: will probe irqs later
    ide0: BM-DMA at 0xffa0-0xffa7, BIOS settings: hda:DMA, hdb:pio
    ide1: BM-DMA at 0xffa8-0xffaf, BIOS settings: hdc:DMA, hdd:pio
hda: IC35L120AVVA07-0, ATA DISK drive
ide0 at 0x1f0-0x1f7,0x3f6 on irq 14
hdc: _NEC DVD+RW ND-1100A, ATAPI CD/DVD-ROM drive
ide1 at 0x170-0x177,0x376 on irq 15
hda: max request size: 128KiB
hda: 234375000 sectors (120000 MB) w/1863KiB Cache, CHS=65535/16/63, UDMA(100)
/dev/ide/host0/bus0/target0/lun0: p1 p2 p3 < p5 p6 p7 p8 p9 p10 p11 p12 >

Re: kernel 2.6 --> no cdrom

the cdrom can be found under

/dev/cdroms/cdrom0

... this is the usual location for cdroms when you use devfs, like arch do use

if you use ide-scsi for burning and there is no cdrw/dvdrw any more:

the 2.6.x kernels support (with cdrtools-devel installed instead of cdrtools) burning directly using ATAPI (IDE)-DVD+-/CD-RW drives without simulating to ide-scsi --- and i think (but not sure because not longer needing) ide-scsi is called something different in 2.6.x

The impossible missions are the only ones which succeed.

Hi,

thanx a lot. But all you tip have failed... but recompiling the kernel finally was the solution....

Re: kernel 2.6 --> no cdrom

Can you tell what the actual problem was with the kernel config? That way the fix might even make it into the stock kernel.

I too have this problem or something akin to it (running the stock kernel2.6): I keep getting permission denied on my cd+-rw/dvd combo (that I don't use much, thank ethernet for that). The fstab-line looks like this:

/dev/cdroms/cdrom0     /mnt/cd   iso9660   ro,user,noauto,unhide  0      0

Re: kernel 2.6 --> no cdrom

well i would not say this is a widespread issue to have to have a fix for the entire arch community. i lost no access or devices upon switching to the newer kernel. this may be a kernel bug not an arch bug.

I'm aware of that, just thought it would be good to get all info on the problem and devise a fix in public so that any poor soul/machine (including me/p4) suffering from it can get cured. Wheter said fix then should be deployed on Arch or if the problem should be reported uptream is a later matter.

Re: kernel 2.6 --> no cdrom

My problem was fixed by removing unhide from the cdrom-line in fstab. Thanks to Pink Chick who suggested this in another thread.
