Yes, I know that: it was necessary in order to resurrect 2.6.25 |
| 7 |
after the big change in Xorg recently: I mentioned it in my OP. |

Aha ! -- it was present for 2.6.25 , so what happened to it ... ? |

I didn't have in in 2.6.25 & it doesn't seem to do anything I want: |
| 21 |
do you have suggestions what it might help with ? |

Yes & lots of diskettes too (they ceased to be floppy long ago: grin)). |
| 27 |
I use one for quick back-ups of files I'm working on. |

No, I didn't have it in 2.6.25 & have just blanked a CD without it. |
| 37 |
The kernel help recommends 'No' unless you have a special reason. |

... THAT's what happened to it !! This is the change in 2.6.29 |
| 43 |
(it could have been in 2.6.26-8 , which I didn't install). |
| 44 |
|
| 45 |
So having enabled these two options, I now get /dev/sr0 |
| 46 |
& can read & write (at least blank) a CD again. |
| 47 |
|
| 48 |
This is another trap in configuring a new kernel, |
| 49 |
ie some needed option is moved &/or needs another enabled to see it. |
| 50 |
Another trap I ran into briefly was a field needing a string, |
| 51 |
which looks as if all it needs is 'y/n' (also in 2.6.29). |
| 52 |
|
| 53 |
Thanks for the careful analysis. I will post a msg to the Forum, |
| 54 |
as there have been several inquiries there which seemed unresolved. |
