Compact flash for routers is sometimes read in PIO mode (rather than DMA
mode) by the router software. In these cases using a generic fast CF
card you can temporarily lock up router, as the router never has a gap
between the PIO interrupts from flash I/O [ie: you copy a big file and
all of your keepalive-dependent (OAM, BFD, etc) neighbours go down; and
this is why you can't use just any CF card in the internal CF slot of a
Juniper M-series)]

So if it does fit your threat analysis, then please provide the original

Cheers, Glen
