5.2 RC and watchdog timeout

Hello everybody,

I just did an update of my 5.1-machine. Everything seems to work 
properly, except my network-devices. They are recognized correctly and 
ifconfig says, that they are active but network isn't reachable and I 
get the error message:

watchdog timeout

I tried two different NIC's with two different drivers (rl with Realtek 
8139 and vr with an DFE 530TX). I also played with different slots, but 
nothing seems to help. So I am wondering if this is a problem with the 
drivers. Both NIC's work fine with Stable and 5.1. Does anybody have 
such a card running with 5.2RC or has anybody a tip how to get them work 
again?

Thanks for your help.
Greetings,
Kay
