Restart problems after writing to mtdblock?

[Paul Nash]

A very good point, well taken.  In the particular case of our board, a power
supply drop out supervisor will cause a hold-off period and the entire reset
system will likely chain off that, but that's pretty specific to our design.

Anyway, we're pursuing the obvious "right solution" and looking at other
mechanisms for interim fixes.  Thanks all...

I wouldn't swear to that. You could feasibly have a power outage long 
enough to reset most of the board, but the flash chips don't draw much 
power and could perhaps retain their state.

Unlikely perhaps, but I wouldn't declare it impossible.
