Thanks Jean-Louis. I'll wait until the patched kernel is issued by
Ubuntu release team as an official update.
Meanwhile I've blacklisted the troubling modules by creating
blacklist-cx8800.conf file in /etc/modprobe.d/blacklist and listed all cx88
related modules (file attached).

Public bug reported:
I do have USB 3 add-on controller and USB 3 external hard disk. The hard
disk works fine on Windows XP and is seen fine on Ubuntu 10.10, but does
not work on fresh 11.04 installation.
When I try lsusb command, the following message appears in the dmesg logs:
[ 1652.340030]

Public bug reported:
After installing fresh Kubuntu 11.04 Natty on my desktop PC, I
experienced some issues with application and process hangs. There is
also a problem with my USB 3 hard disk. These sort of problems did not
happen on Kubuntu 10.10 installed on the same PC (on separate
partition).
** Summary changed:
- Random process hangs after clean Ubuntu 11.04 natty install
+ Random process hangs after clean Kubuntu 11.04 natty install
