Perhaps those chips are part of the problem. And we can explain why on my U2/SMP (Uii@296MHz), I cannot reproduce=20 the bug. I only have Uii@296 MHz and Uii@450 MHz, and I cannot switch=20 CPU's between my U2 and one of my U60 (I need a running U2). If you=20 want, I can open a ssh access on one of my U60 to do some tests. What's cache size on your CPU's ? 450 has 4 MB, 296, only 2 MB. Gavin, what are your CPU's ? Regards, JKB
