Comment:

 sdhci.fth is not maintaining a count of simultaneous opens, so when copy-
 nand opens the  .crc file and then closes it, the close operation turns
 off the host controller.

 The fix is in svn 811.

 Workaround:

 ok  patch noop ?open-crcs  copy-nand
 ok  copy-nand  sd:\os656.img

 That disables the CRC check, which prevents the bug from happening.
