Hi

Desccription of the problems:
1.Problems at DMA initialization. See dmesg.
2.After doing a compilation or an updatedb the system
 become unresponsive for some periods of time while 
the cpu is 100% system. Also there is little free
 memory. If i kill the updatedb the system come back 
to normal. However the memory is not freed. The cache
 is too small to explain the "missing" memory. After
the updatedb (or big compilation) has been running
 for some time,if i issue a simple command on a
 terminal (like ps axuf) it takes a couple of 
seconds to complete, while the system is not 
loaded (the only running tasks are updatedb -- 
or big compilation -- and top).
Here are the top outputs. The last one is when i
killed
the updatedb script.
