Jason, do you get firmware loading fails on boot with the PCI device?

There needs to be a delay put in the firmware download of at least 250uS
after each write, but this does not solve the corruption.

I have tried everything, but all of them fail to get rid of the
corruption on the first frontend when the second frontend starts and
then corruptions every 5 seconds or so. These only come through demux on
endpoint 84 and are not caused by any other frontend operations.

Trouble is, on a Nvidia motherboard I have it does not do it at all and
all applications work without any troubles.  This seems to suggest a USB
motherboard driver issue.

However, the frontend lock does make it at least work on Myth TV.

I am continuing to look into it.
