Bug#220529: acknowledged by developer (RE: sarge installer disc, beta1, missing symlinks)

[Vincent McIntyre <Vince.McIntyre@atnf.csiro.au>]

This bug has not been resolved yet, as of sarge RC1.

There is some problem with the CDROM drive and DMA, which results in
the symlinks on the installer disc not being interpreted correctly.

For the installer kernel, the best resolution is to set
CONFIG_IDEDMA_ONLYDISK=y. There's been discussion of this on debian-boot,
but no move to do it yet. However you may still have the problem in
"production" kernels if people have this sort of hardware.


The goal, at the point in the install process at which this bug appears,
is to detect a disc in the cdrom drive, mount it, and confirm that
the disc is a good sarge installer disc.

A workaround that seems to work is to try mounting the disk again.
I have no idea why this should work, but it does.
Patches to cdrom-detect which do this (and other sanity checking)
are slowly taking shape, see bug #265612.

This bug should be merged with #250323, it's the same misbehaviour.

Vince
