eth0 is the 3com onboard on the a7n8x deluxe...

Having finally woken up (me not the pc), uptime here is now 12 hours..
(without the CPU Disconnect athcool run, just the kernel patch). I did
run the athcool program to check the result though:

nVIDIA nForce2 (10de 01e0) found
'Halt Disconnect and Stop Grant Disconnect' bit is enabled.

Do others have the same value 10de 01e0 when they run athcool stat? Even
with the same motherboard (a7n8x deluxe)?

Im running a grep -R kernel /usr/* and another grep on my 4gb DVD and
compiling a Qt 3.2.3 upgrade now.

For me idle time never seemed to be a problem which I guess relates to
the CPU Disconnect on low usage/low power issue

Perhaps my motherboard and cpu doesnt have a problem with disconnect and
just the IRQ issue, perhaps because its only a few weeks old. It would
make sense in some ways given that my system has only one of the
problems given the uptime I have been able to reach.

My hangs have always been when I have used the PC.. and often completed
a task and then a few seconds later it goes.

Will see in time I guess
