Problem with saturn since 2.6.29 (debian kernel).

Problem with saturn since 2.6.29 (debian kernel).

[Sébastien Bernard]

I'm running on linux-image-2.6.29-2-sparc64-smp on an U60 (2x Uii 450mhz).

I'm on SID and I had quite a lot of problems with my ethernet controler.

Here's the references of the controler :
0000:00:02.0 Ethernet controller: National Semiconductor Corporation 
DP83065 [Saturn] 10/100/1000 Ethernet Controller (rev 30)

PCI Id is 100b:0035.

The Kernel reported the following problem :
[1684214.274488] eth1: Link down
[1684214.274512] eth1:reset called in cas_abnormal_irq [0xa721000]

The machine was working ok with 2.6.28-7-smp kernel.
Transfert are slow (~ 4-7 MBytes/s) and pauses at regular times.

On 2.6.30-1, it goes worse. Link goes down and up every few seconds, 
making the work
a nightmare.

Is this a know problem or should I report a bug for this ?
