The one strange thing is that it seems that it's not hanged; since the X pointer moves in 3-5 seconds intervals (it even change the shape in the window's corners). It happens without X too; but as i said nothing survives... no oops, sysrq, nmi messages, doesn't answer to pings... I know by the fans' sound that the cpu usage goes to 100% I'm thinking of a hardware failure too (but the odd X behaviour makes me hesitate); since i don't remember that it failed under 2.4 that i remember of...this box didn't run a lot of 2.4 kernel though. The box passes memtest86; it's a 2x800 box, ide disk, 256 ram; VIA chipset...just in the (very strange) case that somebody has exactly the same box and they have/don't have the same problems.
