I tried about 25 times and had no chance to trigger the BUG().
Could you please provide a binary image of your FLASH partition, which
triggers the BUG() ?
Reboot. Do not mount /flash and do a
cat /dev/mtdX >flash:img
If this is NAND, you will get a bunch of "Reading without ECC is not
recommended" warnings. Ignore them :)
Thanks.
