Hmm... ICH7. I recently had a different bug report on < ICH7 (don't remember whether it was 4, 5 or 6). In that case, the drive went completely offline after resume. It never came back after retries. It seemed like the device needed hardreset after waking up from sleep which we currently only support for >= ICH8). Mark, you played with the hardreset bits in PCS (right?) register. What do you think about adding it? Last time I played with it, the presence detection seemed unreliable so hotplug might not work too well but as long as the hardreset itself works we can augment it with follow up srst for cases like this. > Besides the SATA drive, with the PATA ATAPI drive, I'm running a > little test of playing a DVD, then performing a suspend, upon wakeup > The movie becomes choppy; > "Basically what I can see over here is"; when the system is wokenup > whatever is left in the ram or memory continues to play, In the meantime > the PATA drive from what I can hear, moves around a little bit thinks > for a second, then starts turning fast, but by then whatever was in > the ram or memory has played, causing the playback to be out of sync, > resulting in a choppy feed. > Idealistically I would like to take the media player, and have it wait > for the DVD to catch up then start playback, Or see If when suspend > occurs (if possible)the lens in the PATA keeps the position, then upon > resume PATA resumes, Or If this is already available try and enable > that feature. What happens if you stop the playing and restart it? Does it play okay? -- tejun
