I've been using compact flashes for years and they always boot nicely with uClinux. 

I've got a new compact flash that doesn't handle the interrupt on boot when given the ID Command.  I have found that with other cards, right after the EC command is sent the interrupts are enabled and everything is great.  But with this card, the interrupts never get turned on.  Is it a problem with the Compact Flash being out of spec? 

I'm enclosing the boot for the cards.

Thank you for your time.
