segmentation fault after detecting module 'alim15x3' for 'IDE chipset support' (6.10 RC)

Thanks for your report. This particular error is often due to a faulty CD/DVD disk or drive. It may help to clean the CD/DVD, to burn the CD/DVD at a lower speed, or to clean the CD/DVD drive lens (cleaning kits are often available from electronics suppliers).

I have done all that you say and check CD before installation. The selftest says the checksum it's ok.
I will retry, but it seems that's not the problem.

I cleaned CD, burned again at minimum speed and the error I have is:
