Hi,

On 2.6.18-rc3-mm2 with hotfixes I get things like the appended one on attempts
to suspend to disk.  It occurs while devices are being suspended and is fairly
reproducible.

Greetings,
Rafael

skge eth0: receive queue parity error
skge <NULL>: receive queue parity error

This stuff comes from the interrupt handler which apparently races with
something.

Maybe the skge driver is not doing netif_poll_disable before clearing the rx 
ring at suspend/down?

Apparently it doesn't.

At least netif_poll_disable is not referenced anywhere in skge.c .
