PROBLEM: kernel 2.4.21-rc5 unpredictably hangs

[1.] kernel 2.4.21-rc5 unpredictably hangs

[2.] During normal operations the kernel unpredictably hangs. I could not find a particular cause to this, however it seems more likely to happen when there are some CPU time consuming applications running, such as gcc, however this happens in other conditions as well. kernel 2.4.20 works fine.
