5.2.1-RC2: CardBus RealTek 8139 based NIC stop working during cvsup

[Rostislav Krasny]

Hi.

I installed 5.2.1-RC2 on a Dell Latitude CP notebook based on Pentium 
MMX 233MHz processor with 128Mb of RAM. There is one cardbus NIC based 
on RealTek 8139 chip. This is a Planet ENW-3504FC CardBus NIC. When I 
run 'cvsup my-supfile' the NIC is stop working short time after it 
started to update the first collection:

I can't ping any host of my LAN or any other but I can ping my self host 
locally. No external host can ping me too. It continue to not work even 
after I stoped cvsup. To make the NIC work I can do ether:
1. run /etc/rc.d/netif restart
or
2. enable or disable promiscuous mode on the NIC by running or stoping 
tcpdump.

Following are parts of `dmesg` and `ifconfig -a` related to this NIC:

rl0: <RealTek 8139 10/100BaseTX> port 0x1000-0x10ff mem 
0x88002000-0x880021ff irq 11 at device 0.0 on cardbus1

         media: Ethernet autoselect (100baseTX <full-duplex>)
         status: active


Interesting, how cvsup could make the NIC to stop working? I tried to 
use 'hint.acpi.0.disabled="1"' but it didn't help.
