Hi Christian,

thanks for the boot log!
Overall, your machine looks pretty "normal". Nothing special.
But regarding DVD drive:

Yes, you have a HL DVD ROM drive on ATA (built-in ns87415 ATA chip).
Here is the relevant output.

This looks normal:

[   22.072309] scsi host2: pata_ns87415

[   24.780519] ata1.00: ATAPI: HL-DT-STDVD-ROM GDR8162B, 0018, max UDMA/44

But here it somehow failed.

[   43.472114] ata1.00: disable device

So, the DVD drive is being disabled by the kernel after some time.
I'm not 100% sure if that is the problem. The messages could also have
been caused by other things. Nevertheless, "disabling device" seems strang=
e.
Is this the official drive which came with the machine?
According to [1] it seems to have sometimes issues with CD-ROMs:

8162b.65076/
Maybe it's worth to test with another CD/DVD drive?

The other aspect:
Even if the drive is failing with "your kernel", could you please
try to boot the CD I mentioned and post the serial console output as well:=
 ?

I would like to know where boot is failing, and if we get at least some ou=
tput on the console.
