Comment:

 gnu sent Lilian the SD card in question.  She found that, under OFS, it is
 flaky on B1, but it works reliably on B2.  She made it work reliably on B1
 by avoiding the switch to 50 Mhz card clock.  I.e. B1 seems to be good at
 25 MHz, but not at 50 MHz.

 This is probably caused by the FPGA-based CaFe chip on B1; B2 has the
 ASIC-based CaFe, which is faster.

 Reassigning to Pierre to decide what to do about this in the Linux driver.
