Hi,

In the function "_ehci_append_qh" do you know if it is the second or 
first call to "usb_pc_cpu_flush" which fails. The pointer which is 
passed as an argument to this function resides in the memory which is 
flushed, so most likely the cache sync operations are not working like 
expected!

What platform is this? Non-freebsd? Did it work before?
