I don't really know, but I can confirm that both 2.2.x and 2.4.x kernels
are unstable on a beige g3 and a bmac equipped b/w g3.  I can crash them
rather easily with regular programs, given a day or two.  I have not seen
similar instability on other machines (dual g4, 7600, all nubus).
Unfortunately, I don't have any time to track it down right now  :(
