Comment 10 for bug 213696

Sounds great - but (after several hours of trying) it still doesn't want to work here.

I've downloaded Intrepid Ibex from: http://cdimage.ubuntu.com/releases/intrepid/alpha-1/ It came with a slightly older kernel, so I updated (using standard repositories / usual method) and the kernel now reports: "Linux ubuntu 2.6.26-3-generic #1 SMP Wed Jul 2 21:54:36 UTC 2008 x86_64 GNU/Linux"

The dmseg output when I try to load a UDF 2.50 formated CD from Vista still reads:
[ 2276.836315] end_request: I/O error, dev sr0, sector 29508
[ 2277.000290] end_request: I/O error, dev sr0, sector 29504

I've tried multiple CDs - just in case of physical media errors. If I select 'Mastered CD' when burning in Windows Vista, the disc reads fine. But every type of LiveCD still fails I've tried different drives. I've tried different versions of Vista. It still resolutely refuses me.

I've also tried UDF 2.01 - which is the default CD format that most Vista users are going to be burning on. This also fails 100% of the time for me - but with a slightly different error message:
[ 2573.620375] UDF-fs: No VRS found

(NB: there's a pen drive being connected and disconnected a few times - that's being used to copy log files across to my PC).

I attach a zip file with the last 25 lines of dmesg output after trying each of the different UDF CD formats.

Any advice / assistance would be very gratefully received.
