Comment 5 for bug 294391

I just remembered another old issue with FireWire iPods which was never addressed in the drivers. (Can't process more than one page table element.) It seems that performance enhancements in the block layer of newer kernels changed that problem from a theoretical one into an actual one.

Alas it looks like there is no sysfs switch or module parameter which could enable a necessary workaround. I will look into this and report back later. In the meantime, please try the two suggestions nevertheless and post your results here. Thanks.
