CD writing fails on P6T motherboard with Pioneer cdwriter

[Yuri]

Ever since I upgraded to P6T motherboard I can't burn any data or audio 
CDs/DVDs.
My dvd-writer ('PIONEER ' 'DVD-RW DVR-112D' '1.21' Removable CD-ROM) 
burned CDs ok on the older motherboard/CPU combination.
And now trying to burn audio-cd I got the log below.

What might be wrong?
