what ethernet card ? lspci output please.
oh wait, does your usb cable modem usually show up as eth1 ?
Which driver does it use ?
On this systen I also have a Via Rhine II that shows up as eth0. There
seemed to be a consistent problem with that driver that was related to
acpi so I switch to the usbnet connection USB CDC Ethernet Driver.
This has been reliable till kernel.315. The caveat being that
kernel.309 was the last to boot on my machine, an EPIA V with a C3.
Kernel.326 boots but the usbnet/CDC Ethernet Driver fails to connect.
Booting with the kernel.309 is OK. During bootup of kernel.326 the
activity led on the modem goes active but eth1 fails to connect. I
notice a variety of usb related complaints on the test list post
Can you "lsmod |grep usb" and paste everything that shows up?
/sbin/lsmod | grep usb
usbnet 22412 0
mii 3712 2 via_rhine,usbnet
crc32 3968 2 via_rhine,usbnet
I think it's a regression in the fresh 2.6 we picked up recently.
The USB subsystem seems toast. The best is to wait for the next
I have the same problem with 2.6.5-1.327smp and my Motorola SB4200E
cablemodem. It worked fine before upgrade from 2.6.5-1.322smp.
/sbin/lsmod|grep usb gives
usbnet 25228 0
mii 7552 1 usbnet
crc32 7808 1 usbnet
i have the same problem with my AMBIT cable modem
( ifup eth0 - fails ) which works just fine on kernel 2.6.3.xxx
Problem solved with 2.6.5-1.349smp in RawHide.
