Gamma ray bursts as source of highest energy particles “all but ruled out”?

In “’Extreme Universe’ puzzle deepens” (BBC News, April 19, 2012), Jason Palmer reports,
The mystery surrounding the source of the highest-energy particles known in the Universe has grown deeper.
The particles, known as cosmic rays, can show up with energies a million times higher than the biggest particle accelerators on Earth can produce.
Astrophysicists believed that only two sources could make them: supermassive black holes in active galaxies, or so-called gamma ray bursts.
A study in Nature has now all but ruled out gamma ray bursts as the cause.
More. Guess it’s down to black holes now.
