PCI status error 0x2a80..

PCI status error 0x2a80..

[Ashish anand]

Hello,
I am experiencing the PCI bus error for a network card(Realtek 8139)
operation.
whenever it tries to transmit packets it prints the error like

eth0: PCI Bus error 0x2a80.

PCI status 0x2a80 as per pci specs suggests pci master and target
abort.
other basic infrastructures like  interupts , pci-dma and cards pci
resources are well in place.also i am able to receive all packets.
I have ensured other pci config registers like Latency timer and
command register are initialised to appropiate values.
pci command has been set to 0x7  ( io + mem + busmaster).

1.what can be other reasons for this to happen ..?

2.if pci master and target abort happens how the card is able to recive
the packets..?

3.does this situation demand pci debugging or driver level debugging?

Best Regards,
Ashish Anand

This is the card that locks up when you try to drive it with maximum
traffic under both Linux and Windows, right?

The 8139 has been driving driver writers crazy over the years.  Too many
too bugy variants.  I remember a guy who had a car number plate with
RTL 8139 printed on it on his wall because he managed to improve the
situation by a few percent ...
