Gday everyone. I have an ASUS K8V-VM motherboard which uses the VIA
K8M890 / VIA VT8237A chipset and it has the Via Rhine II integrated
NIC. I have a problem where the kernel shuts down IRQ 23 as part of
ACPI activity and from there on in I get continued eth0 timeouts on my
NIC. The via-rhine module is on IRQ 23. My wired ethernet will not
come back from doing a network down / up, the module has to be
manually removed and reloaded or a reboot has to occur to fix it.
Currently Im on Ubuntu Hardy 2.6.24-19 but I also did my own compile
of a vanilla 2.6.25.8 kernel as a test - it has the same exact
problem.
I'm reluctant to turn off ACPI all together and was hoping a fix might
be able to be done please? I have spent some days looking for fixes
but none appeared. I'm learning Linux but I will follow any diagnostic
procedures that might be required to give people more information.
The kernel log looks like this:
