I have seen cases where -p1024 was too big, where I only saw stability 
at 512 and one or two notches less.  Tell us what happens with 512.  
What is your CPU and RAM?

I wouldn't file a bug report yet, because this is probably not a bug in 
any code, it's probably configuration of your machine we need to figure 
out.  Can you post 'lspci -v' and 'lsusb -v' to this list?
