Intel X58 chipset on an Asus P6 Deluxe. We are using the onboard controller.

test_usrp_standard_tx reports
xfered 1.34e+08 bytes in 4.19 seconds.  3.2e+07 bytes/sec.  cpu time = 0

Identical behavior on another machine, which has Athlon 64 X2 and hence 
different mainboard and chipset, definitely no Intel chipset. But I am 
not at the institute and can't tell you the controller name at the 
moment (but tomorrow, if you need it).
