Sorry. Ignore the last message.
There's several places to turn on debug for this (MTD and JFFS2) and,
apparently, those messages are just debug. Because the debug is written
to the log file it makes everything veeerrrry sloooow. I rebuilt the
kernel with all debug off and things seem to be working fine now.
