Nano 1G: ATA DMA broken in some devices aka "works only when cooled"

<< < (2/2)

maraz:
As there seem to be other cases of this bug appearing, it would be interesting to see if its appearance is tied to a specific model of chips. Attached is the ATA identify info of my faulting nano dumped by Rockbox.

Others suffering from the ATA problem, please go to System -> Debug -> Dump ATA identify info, this generates a identify_info.bin to the device root which you can then post here.

Maybe also people without the problem (but still with a 1st gen nano of course). I assume those will be useful too to see what the actual important differences are. Please say if it's from a nano with the problem or without though.

Heat exacerbated memory issues have been an issue with some Nanos for at least three years:  (maraz is no stranger to this)

This is likely a n00b question, but I suspect this is the problem with my ipod, but how do I apply the .patch file to my build? Thanks guys

Buschel:
ATA DMA is switched off in rockbox 3.8.1 and all Trunk builds from r29476 on (March, 1st, 2011).
