Finally it was a graphics card issue. It can be solved by
setting an option in XF86Config.

Copying from savage manual (man savage):

Option "ShadowStatus" "boolean"
Enables the use of a shadow status register.  There is a chip bug in the
Savage graphics engine that can cause a bus lock when reading the engine
status register under heavy load, such as when scrolling text or dragging
windows.  The bug affects about 4% of all Savage users.  If your system
hangs reg- ularly while scrolling text or dragging windows, try turning
this option on.  This uses an alternate method of reading the engine
status which is slightly more expensive, but avoids the problem.
Default: off (use normal status register).


Thanks for the help,
