Looks the problem is about ehci host controller driver, because the 'csw' completes very slow on lucid release, but no such thing on Oneiric, see below trace: Lucid trace: f6305800 716082026 S Bi:1:003:1 -115 13 < f6305800 716093942 C Bi:1:003:1 0 13 = 55534253 71000000 00000000 00 Oneiric trace: f3ea8580 2484657937 S Bi:1:002:1 -115 13 < f3ea8580 2484657945 C Bi:1:002:1 0 13 = 55534253 26b20000 00000000 00 Just have a quick look at Lucid ehci patches and found most of ehci unlink/queue patches have been merged to lucid, so could you confirm that you have updated to the latest Lucid release? If not, please try 'sudo apt-get update&& sudo apt-get dist-upgrade', then redo the test to see if there are any improvements.
