From #0889:

"I have noticed some strange system behavior. When i try to build a
kernel (medium load) - X, keyboard, mouse and sound hangs."

Note that ping is handled in interrupt or softirq context. So something has
locked up. Try without X? Or perhaps attack a serial console/netconsole, and
when it hangs, use Sysrq to dump the process' states.
