I tried a 30s anti-skip with 16s spindown and it failed from time to time. I also tried a 30s anti-skip with 31s spindown and after many test it did fail on one occasion. However the 15s anti-skip with the 16s spindown works fine till now.

It happens on my H120 too. This with a low-bitrate file, needing 10-15% boost to play (using default settings). It looks like the codec thread is blocked from reading while the disk spins up, causing the PCM buffer to run dry. That enabling crossfade fixes it makes sense then, since the PCM buffer is much larger in that case.

It wouldn't surprise me if this affects most/all swcodec targets with a hard drive...

A possible explanation, but that doesn't explain why this has only happened recently :(

I changed the ATA driver recently-ish, but the changes would not cause spinup to take longer, or affect whether the driver yields...

I think I found the problem, and the fix is in r24968. Haven't looked up when it was introduced though.

Edit: It was introduced in r23680.

So if the issue is new and didn't exist in version 3.4 the solution would be easy:

Just where can I find version 3.4 please? In the old releases archive I found only things related up version 2.5.

I am really embarrassed to ask so stupid questions.

Try a current build as Lear thinks the problem has been fixed.
