Unfortunately it's not doing too well. When building a kernel with 'make -j 8' on my AMDX2 64bit, the screen repeatedly locked up for several minutes at a time,and my music player also froze. In total the full kernel build took over 80 minutes, normally it's only about 15. However the machine seems to have recovered correctly, & now everything is back to normal. Maybe it does need the congestion handling after all? regards Richard
