Kernel Oops while trying to ping, kernel 2.4.18.
I brought down eth0, brought it back up, and adjusted routing tables,
and then tried to ping my ISP, connected to eth0. At the time I had
only the usbnet module loaded, and I had usb0 up, which is a usb
connection to my iPAQ handheld running linux, kernel 2.4.16. When I ran
ping, right after the PING ip.address... line, I got a kernel oops. My
first thought was a problem with usbnet, as if I do some heavy activity
over the usb0 link such as X through ssh I occasionally get a lockup.
(Can't do anything, see no oops or anything, can't ssh in).
Modules loaded at time: usbnet
Networking info: eth0 was up, 3com 3c905b card. lo was up. eth0 was
up, usb connection.
Kernel 2.4.18.

Motherboard is a MSI KT3 Ultra (Via KT333+Via VT8233a). IDE drives,
.5gb ECC DDR ram, expansion cards are: Radeon 7500 in AGP, 3c905b NIC in
pci, SB Live! in pci, no ISA slots. I've only had the lockups when
doing X over ssh in kernels 2.4.18 and 2.4.17 I think. This box locks,
but the iPAQ is fine.
