Thanks John for the response. This makes total sense as my functional
testing has also proven this.

Everything runs and seems to work ok when booted from the Compact Flash

Does anyone have a clue as to how to solve this or is it something I can
It can be ignored. It only happens for removable devices (hence CF and
not HD). After a timeout period, cached data for removable devices is
invalidated, which means a physical read of the device to refresh it.
So not an error, normal operation for removable. If your CF is wired
in such a way as to not really be removable (eg on-board vs in a PCMCIA
card) you can use the option “eide -R” to have the driver advertise it
as non-removable, which will have better performance because the cache
timeout/invalidation/refresh will not be performed.
