[Solved]Kernel 2.6.21 and network card troubles

After upgrading to 2.6.21 my network card RTL8139 doesn't work. I can't send any ping to my network. Then I roll back to 2.6.20.7 and upgrade to 2.6.20.10 - all works fine

# dmesg|grep eth0
eth0: RealTek RTL8139 at 0xdee2c000, 00:90:f5:31:4b:c0, IRQ 10
eth0:  Identified 8139 chip type 'RTL-8100B/8139D'
eth0: link up, 100Mbps, full-duplex, lpa 0x45E1

Does 2.6.21 is 'buggy' kernel now?

This is not a kernel bug, this is a feature. I set my PDA in cradle and new 2.6.21 kernel found my Dell Axim X51v

usb 2-1: new full speed USB device using uhci_hcd and address 2
usb 2-1: configuration #1 chosen from 1 choice
usbcore: registered new interface driver cdc_ether
eth2: register 'rndis_host' at usb-0000:00:1d.1-1, RNDIS device, 80:00:60:0f:e8:00
usbcore: registered new interface driver rndis_host

But if I set PDA in cradle and then power on my laptop, PDA recognized as eth0 device and will be configured with parameters, defined in rc.conf. Internal NIC recognized as eth1.

Solution: do not attach PDA before or during boot process

Re: [Solved]Kernel 2.6.21 and network card troubles

Anybody can suggest a solution: How to configure internal NIC always as eth0, independently attached PDA to laptop or detached from it before power on ?

See http://bbs.archlinux.org/viewtopic.php?id=32588. There be two ways (ifrename or udev) to do this and both could solves the problem for you.

Thnx, ifrename is good to me. I like BSD-style of naming devices.
