I would like to emphasize that this problem is intermittent; however, I am noticing an increased frequency whenever I have 2 devices that have sound capabilities, in particular microphone sound devices. Similar to Joël Wijngaarde's (original bug reporter) report I am seeing in the syslog messages the following:

The "sound/usb/clock.c:233" report line repeats several times (> 15 times) and the overall system response time noticeably slows to a grind. The frequency of this intermittent bug occurence appears to be more often when I have more than one audio input device connected:
# lsusb
Bus 001 Device 002: ID 046d:0991 Logitech, Inc. QuickCam Pro for Notebooks
and my native mobo audio device (from "lshw")

I am observing this bug on a "Lenovo Thinkpad T60p" using the following:
