Do you know precisely which Realtek chip you have? You'll have to look at the number printed on the chip itself: the PCI device ID is not quite enough detail.

It would be good to know if this patch also fixes the problem:

Code:

--- a/src/drivers/net/realtek.c
+++ b/src/drivers/net/realtek.c
@@ -997,7 +997,7 @@ static void realtek_poll ( struct net_device *netdev ) {
                realtek_poll_tx ( netdev );

        /* Poll for RX completionsm, if applicable */
-       if ( isr & ( RTL_IRQ_RER | RTL_IRQ_ROK ) )
+       //      if ( isr & ( RTL_IRQ_RER | RTL_IRQ_ROK ) )
                realtek_poll_rx ( netdev );

        /* Check link state, if applicable */

i.e. commenting out the check for IRQ_RER|IRQ_ROK but leaving in place the "if(!isr) return;" near the start of realtek_poll().

If this patch does work to fix the problem, then it means that the chip is reporting some kind of interrupt that we need to add to the list in the IRQ_RER|IRQ_ROK line.

If this patch does not work to fix the problem, then it means that the chip is not reporting any interrupt, i.e. that the chip is broken.

Sorry about late.
It's not possible to open up the pc case.
From the lshw, it says RTL 8111/8168/9411 PCI Express.
From the Windows device manager(in INF section), it says RTL8168G so I guess it's 8168 chipset.

Also I have interesting results from quick patch.
- w/o patch, it slows to display Windows logo(black screen after sanboot command) and result in slow boot. (boot over 1 min)
- by removing "if ( isr & ( RTL_IRQ_RER | RTL_IRQ_ROK ) )", fast to display windows logo but slow to fade out. (boot about 40 secs)
- by removing "if ( ! isr ) return;" and "if ( isr & ( RTL_IRQ_RER | RTL_IRQ_ROK ) )", fast to display and fast to fade out logo. (boot about 20 secs)

Hope this helps.
