Comment 1 Dave Jones 2004-04-16 18:52:24 EDT
what ethernet card ? lspci output please.
Comment 2 Dave Jones 2004-04-16 18:53:34 EDT
oh wait, does your usb cable modem usually show up as eth1 ?
Which driver does it use ?
Comment 3 Paul Coleman 2004-04-16 22:43:42 EDT
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
Comment 4 Warren Togami 2004-04-18 16:30:16 EDT
Can you "lsmod |grep usb" and paste everything that shows up?
Comment 5 Paul Coleman 2004-04-18 20:16:34 EDT
/sbin/lsmod | grep usb
usbnet                 22412  0
mii                     3712  2 via_rhine,usbnet

Comment 6 Pete Zaitcev 2004-04-19 14:51:27 EDT
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
iteration, IMHO.
Comment 7 Miguel Dardenne 2004-04-30 21:16:11 EDT
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
Comment 8 Nadav Kavalerchik 2004-05-03 14:57:22 EDT
i have the same problem with my AMBIT cable modem
( ifup eth0 - fails ) which works just fine on kernel 2.6.3.xxx
Comment 9 Miguel Dardenne 2004-05-07 07:18:48 EDT
Problem solved with 2.6.5-1.349smp in RawHide.
