cdrom recognition on kernel 2.6.8.1

cdrom recognition on kernel 2.6.8.1

[Lars Täuber]

Hallo everybody,

I'm not subscribed to this list! But I read the archive from time to time.

In my linux box is a teac IDE CD-Rom drive. This is only recognised when no audio cd is in the drive while booting.
Is this a drive failure, or a kernel failure?

I didn't find any other on the net with the same problem. So hopefully someone of you can explain?

Did 2.6.7 work? The ide-probe isn't finding your drive, that's very odd.
I think this is an issue with your hardware, not Linux. Perhaps you can
use the drive if you add hdc=cdrom to your boot line.

Dear Jens,

the problem accours also under 2.6.7.
But the hdc=cdrom options solves this problem (under 2.6.8.1):

As written bevore the drive is not recognised only with an audio cd in it.

Thanks

I've seen Teac drives blocking the Windows XP boot process when
certain discs are inserted. There were even freezes when copying files to
hard disk that did not occur when a different drive was used.
(Wasn't my machine, can't test anything.)

Obviously Teac's firmware has some issues.

I've  had some  issues  with an  old  TEAC SCSI  CD  writer which  was
somewhat weird:

On bootup it  would only read CDs if, after  bootup had completed, one
switched  off its  power  and booted  it  again. (SCSI  RESET was  not
sufficient.)

So yes.
