> The 2.6.24-12-generic (I think, may be -386) causes my machine to lock up
> (hard) after about 5 minutes. Generally I was under X, there is no specific
> program I was using at the time it locked up.

> The hardware is completely stable & has been for the last 3 years with
> ubuntu, and still is with hardy & the gutsy kernel.
>
> Another thing I noticed is that something in the initrd keeps the machine
> from booting for at least 2-3 minutes. It's definetely before running
> scripts in the /etc/rcS.d folder, I have not traced it in the initrd. After
> booting all is well until it locks up.
>
> The hardware is a Dell C400, Intel chipset, Intel graphics (i830), 384MB of
> RAM and an atheros wireless card.

> lsb_release:
> Description: Ubuntu hardy (development branch)
> Release: 8.04

> It's completely reproductible, the freeze takes out the whole kernel (no
> reply to ping from network). Any suggestions on how to trace it? I have a
