    I've a similar hang; no oops; no sysrq; no NMI messages;
    But mine only happens under 2.5; since long time ago.
    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.
