Paulway mixes not Karma friendly, battery killer

I decided to test my Karmas battery life, and well, got about 3.5 hours... And it was that low due to what seems to be a caching problem. My test playlist was all 20 of Paulway's mixes, starting out with the Infinity Mix. This clocks in at almost 4 hours, and what I found is the Karma was constantly spinning up the hard drive, then spinning it back down. Once I noticed this, I quickly switched over to a more normal CD type playlist with short songs, and the hard drive stopped its constant spinup and spindown cycle.

This is with 1.41 firmware.

Sounds like a bug in dealing with songs that are larger than the max cache-area. Perhaps related to cross-fade support?

I did try to find the rough time problem, but the battery died before I could. The drive worked normally on the 74 minute tracks, but definitly didn't like the Infinity Mix. PaulWay has one at 120 minutes, going to see what happens with that one, once I get home and can put the Karma back in the dock.

Are they mp3 files ?

It's an MP3, yes. Paulway has it up for download here. It's 266mb, and 3:56:55 in length. I tried playing his shorter mixes (none have been longer then this one, yet), and none of them caused this issue, only the Infinity Mix.

I believe there was a bug involving files >2h long which has been fixed in 1.6x...

Good to hear Hugo. When 1.6 comes out, I'll try it and see if the same result occurs.

Also, I'm going to tinker around with GarageBand a bit and see about making a 4 hour long track to confirm it is indeed time based, and not just something weird with that one file.
