Comment 40 for bug 417842

i updated to the latest build from 10/22 no change bug still occurs with my Dell XPS1530 / Nvidia 8600.
i thought it may be the Nvidia hardware drive, replaced it with the software version ...no difference
thought it may be the pulse audio driver ... removed it no difference
also thought it may be my Virtualbox installation, but it does still happen after Virtualbox is shut down,
the oonly thing i didn't try yet (the "only" of may haha, sorry of cause much more possibel) might be to remove the vboxdrv ?
unfortunately the bug seem to be intermittent so its difficult to isolate

any help or advise would re really really welcome
