Do you have 4G or more of memory? Yes (I have written it in my previous mail) - I have 8 GB of RAM. Can - for example - a non-linear memory (i.e. the memory hole remapping= ) be a problem? IIRC, I have it set to "on" in my BIOS setup. : Some motherboards are crap and don't actually allow DMA from high mem= ory. With 8 GB only half of my RAM is below the 32-bit barrier, so I guess if this was a problem, I would got this error more often (every second packet on average?). OK, I will try to poke my HW vendor.
