Bueno copio y pego lo dicho, leerlo bien ya que no está probado en la nuestra, pero los sintomas son casi identicos.
"""""""""""""""""""Parche para corregir congelaciones en el sistema
Esta destinada para los ports de ics de la 7510 y 7500, pero el error tambien ocurre en stock roms de 7310 y 7300, lo he probado y parece que se corrige, el error en si consiste en que el sistema operativo se queda congelado forzando un hard reset o un reseteo "en caliente" pulsando el boton power durante 10 segundos, ya que no responde de ninguna manera
https://play.google.com/store/apps/details?id=com.issess.fastforcecloseFreeze instead of FC in ICS ports from p7500 p7510 [FIX] Update 2012-08-22: I'm cleaning up this Post #1 to summarize the thread.
SUMMARY
There is a bug in (at least some of) the Samsung stock ICS for P7500 and P7510 (Galaxy Tab 10.1): the system freezes when an application force closes (FC) and does not show the typical "Close or Report" dialog; you need to reboot your tab to continue.
This bug occurs on the 10.1 tabs and also on 8.9 tabs using the ports that kaltt_kaffe made (P7300 / P7310), which are based on some of the first released ICS ROMs for the 10.1 tab.
This thread was started to discuss/discover the issue & contains solutions.
SOLUTION:
Ideally you first confirm you have this issue. Then see post #8 and flash the zip attached to it.
PS: there is a dev in the 10.1 forum who (reported to have) fixed this another way - but we haven't figured out how he did it yet...
HOW TO KNOW IF YOU HAVE THE BUG, AND/OR FIXED IT?
- (needs root) You can download this app from market: Fast Force Close. Click on "Crash Test". If your tab freezes, you have the bug. You need to press the power button for 10 seconds to turn off your tab. Then press again to start up. If instead you see Force Close "Close or Report" dialog, you are bug-free 
- if you don't have root, or don't want to install the app mentioned before, then you will only know if you see an actual Force Close dialog, or instead your tab is freezing from time to time. """""""""""""""""""""""""""
