Public bug reported:
Sounds funny, but it's real. Sometimes network traffic stops coming
trough. And it only continues when I move the mouse. And it only
continues as long as I move the mouse. So stop moving means network
traffic stalls again.
It's hard to say anything more detailed on this. Here is what I
observed:
It seems to happen only after resuming from hibernation. (Though I
mostly start the machine by resuming from hibernation, so this doesn't
necessarily have to mean anything)
It's not tied to X11 applications or apps running from within X11. I
have to be on a VT running X11 when moving the mouse. I tried switching
to a text VT and doing a ping, but nothing happens even though I move
the mouse. Only when I switch to the X11 VT and move the mouse, ping
data on the text VT gets through.
I can't tell at the moment if it is tied to a certain network device or
driver, but I don't think so. It definitely happens with the ethernet
device, not sure about wifi (my AP is broken at the moment). Unloading
and reloading the ethernet driver didn't help.
I can currently "fix" this only by doing a full system reboot (only
hibernating and resuming doesn't help).
My system:
I'm using hardy 8.04.1, all updated with kernel 2.6.24-21-generic.
The machine is a laptop, Intel Centrino first generation, Pentium M 1,4GHz.
Wifi is "Intel Corporation PRO/Wireless LAN 2100 3B Mini PCI Adapter (rev 04)"
using driver ipw2100.
Ethernet is "Broadcom Corporation BCM4401 100Base-T (rev 01)" using driver b44.
Mouse is a Logitech USB mouse.
Graphics adapter is "ATI Technologies Inc Radeon RV250 [Mobility FireGL 9000]
(rev 01)" with radeon X11 driver.
If you have more questions or suggestions what else to try, I'd be happy
to help.
