Description of problem:
I'm running Red Hat 7.2 kernel 2.4.7-10 installed clean on a Dell Dimension XPS
T500, connecting to the internet via USB with a Turbonet cable modem on eth0.
My ip connection is fine (ping OK, ftp OK) until I launch an hhtp URL
in a browser - any browser. Then the browser churns and eventually
returns "timeout on server". eth0 is then dead - ifup fails and the
following two diagnostics are appended to the syslog:
Apr 21 15:38:05 pc2-oxfo3-0-cust67 kernel: usb-uhci.c: interrupt, status 3, frame# 0
Apr 21 15:38:05 pc2-oxfo3-0-cust67 kernel: CDCEther.c: read_bulk_callback failed
submint rx_urb -32
The boot log contains 2 earlier problematic messages whose relevance I
Apr 21 15:35:26 pc2-oxfo3-0-cust67 kernel: CDCEther.c: eth0: set too many MC filters
Apr 21 15:35:54 pc2-oxfo3-0-cust67 xinetd: warning: can't get client
address: Transport endpoint is not connected
This cable modem setup functions fine for Win98 dual booted on the
Version-Release number of selected component (if applicable):
Steps to Reproduce:
1. Ensure that system has functioning internet connection for ping,
commandline ftp, browser ftp, via Turbonet cable modem on USB to eth0
2 Open any browser and enter any http URL
Actual Results: Browser churns, eventually returns timeout of server.
Ping <any remote address> returns "destination network unreachable".
/var/log/messages has 2 new diagnostics as per summary.
Expected Results: Browser should have returned web page from requested URL
Is it possible to install kernel 2.4.9-34 and check if that works?
I understand it may be difficult if Internet does not work...
But I do have serious doubts about CDCEther in ancient kernels.
In fact the best would be to go directly to 2.4.18-3
(shipped with RH 7.3).
I installed 7.3, kernel 2.4.18-3 to see how that fared. It has
It's slightly better. I can still browse ftp URLs, and can't browse
any http URLs, but now, when the browser times out, I still have a
functioning network on eth0. But since I can't get the Web, this is
still a Windows household.
Suspect diagnostic now appearing in the boot log is:
Jul 2 13:29:07 pc2-oxfd1-3-cust88 kernel: CDCEther.c: eth0: set too many MC
filters, using allmulti
And after http browsing has bombed, I get the like of this:
Jul 2 13:32:18 pc2-oxfd1-3-cust88 kernel: usb-uhci.c: interrupt, status 3,
repeated many times with different frame numbers.
I tried out Mandrake 8.2 in between R.H. 7.2 and 7.3, and the
behaviour was the same as I've described here.

Possible fix from Brad Hards
Requestor, please identify if you can build kernels and test patches,
or you need a binary RPM.
Can you try a kernel from beta (2.4.20-2.24 currently)?
It has the infamous '^' instead of '%' in CDCEther.c
