 On an XO-1.75, running Q4A07 and either a Transcend 4GB or Adata 8GB
 internal SD card, I've seen corruption of large files sitting on disk!
 This was verified on both A1 Tinderbox and A1 #7.

 I'm running either the OS1+ demo image with cjb's latest kernel (from
 12/15) or OS2.   I download a 250MB ZIP file over WiFi, using wget.
 After downloading, md5sum indicates that the file is identical to that on
 the server.   I use unzip to unzip the file, and see CRC errors (in
 different places when run multiple times).  When I then run md5sum over
 the ZIP file, the MD5 hash has changed!
 It no longer matches that of the file on the server.

 This has been repeated multiple times, on multiple hardware platforms
 using different SD cards.
