[Bug 571806] Re: Lost interrupts/resets on ATAPI DVD

[Alex Sidorenko]

Problem duplication
------------------------

It seems that the problem manifests itself only when writing DVDs at
least at speed 8x. I met it 3 times out of 3 when I burned DL-DVD at
speed 8, once when 35% was done, two other times when 70-80% was done.

I cannot duplicate it at speed 4. Using a rewritable DVD+R I
burned/verified the same ISO 6 times in a row without any problems.
Unfortunately, I don't have any rewritable DVDs that work at speed 8 for
experimentation.

So it seems that the problem is triggered by high transfer rate to ATAPI
device (increased interrupt load?).

Regards,
Alex
