Comment(by corbet):

 Replying to [comment:16 dilinger]:
 > The more memory that's available, the higher the chance of the 600kB (or
 so) contiguous memory that we need being available.  Still, I'm surprised
 that it was unable to find enough memory with 30MB free.. but then again,
 that's 30 out of 256MB..

 I'm not surprised at all - Linux tends to fragment memory quickly, and the
 DMA buffers are a set of unfortunately large contiguous allocations.  I
 had assumed that this would be a problem from the beginning; that's why
 the pre-allocation option is there.

 The anti-fragmentation work in 2.6.23 should help a bit, but the
 fundamental problem remains.
