We have a beta firmware ready which cures this problem, which is - to stress this - not a bug inside DENEB, but Buster 11. Apparently up to now nobody ever stressed Zorro III DMA on Buster 11 in the way DENEB does.

Thanks for taking the time to write Michael. Kind of surprising more people haven't noticed the ZIII/Buster 11 DMA issue with Deneb.
Regarding this firmware update... you're talking about within the Deneb card right? So there's now or soon to be a workaround for our "defective" Buster 11's in using Deneb in DMA mode? Nice we have the option of flashing firmware than waiting forever for a new Buster chip
Love to give that a try when it's ready...
