Please set ips =0 and try again..

What does that mean?

I can trigger the grinding-to-a-halt reliably with "ips=0" - it only
takes a couple of hours of network traffic. Also, I don't want to try
the driver you sent me because the version in the kernel needs fixing
not some out-of-tree codebase.

I got a chance to review the rtl8192se part of the changes in that 08/16/2011 
version. Attached is a patch to update the kernel version.

A prerequisite is:

     rtlwifi: Combine instances of RTL_HAL_IS_CCK_RATE macros.

     Three drivers, rtl8192ce, rtl8192cu and rtl8192de, use the same macro
     to check if a particular rate is in the CCK set. This common code is
     relocated to a common header file. A distinct macro used by rtl8192se
     with the same name is renamed.

I have run the new version for a couple of hours without problems. Perhaps it 
will cure your difficulty, but I am not optimistic.
