Sony /liteon and Kprobe



Hi guys I,m a newbie so please tolerate my ig.I bought a Sony dw22a and it
worked ok on the original bsy2 burned a few movies etc,I had the P.C apart for something else and on reassembly it wouldnt read movies any more.So after reading the forums i,ve burnt it to the lite-on firmware with the led fix etc.
It now reads movies again but seems reluctant to burn to cd-r discs.Also when I
try to analylize the player with Kprobe the drive query just crashes with invalid page fault in Kprobe etc.Should I flash back to one of the bs firmwares to use
rite cd-r discs?
