Linux Alpha - SX164 Memory

Processes terminate with signal 11, segmentation fault or other unusual errors without special reason
This problem is known for all kernels up to 2.2.5
It seems to have to do with usage of threads and large memory chunks. The complete system becomes unstable and processes may stop without any reason!
A fix is not yet known.
Test that shows this error: Playing a MPEG-I stream using the mtvp MPEG player and compiling a kernel at the same time causes either the player to crash, the compiler to seg-fault or sig-11, or any other random to process to die.
x11amp seems to show the same effect which proves the thread theory because the only thing both mtvp and x11amp have in common are threads (and X11 :)
