Public bug reported:
Binary package hint: firefox-3.0
The "source package" appears to be the rt61pci module or perhaps one of
the modules on which rt61pci depends. This is the module that is
associated with my PCI Card according to log messages (I think SE
indicates version, so this is a verison of the RT2561 chipset). My
system is up to date as of today. Problem persists.
lsb_release -rd gives:
Description: Ubuntu 9.04
Release: 9.04
I expect my system to be able to suspend or hibernate without hanging.
I also expect my wifi to still be working when I wake from suspect or
hibernate.
What happens instead:
When I boot my machine, the wifi card works. I can connect to the Internet.
But:
a) If I suspend or hibernate, about 2/3rds of the time the system hangs either
as it is being suspended / hibernated or as it is waking up. About 1/3rd of
the time, it comes back, but now wifi is not working and at times no device on
my PCI bus is working (e.g., the CD drive won't work). Trying to restart wifi
at this point by restarting networking or the wlan0 interface doesn't fix the
wifi.
b) I seem to avoid the system hang altogether and can suspend / hibernate a
few times (but not always) and still get wifi back by issuing the following
commands:
Before suspend:
sudo ifdown wlan0
sudo modprobe -r rt61pci
After suspend:
sudo modprobe rt61pci
sudo ifup wlan0
I'm attaching a file showing what my message log shows after I suspend
and unsuspend with the CWP-854 PCI card added to my system (on an
instance when the system does not hang, but wifi becomes unusable). The
file then shows another set of message log output for when the card has
been removed from my system. Between the two of them, it should be
possible to figure out just what additional error messages are being
generated by the card (there are error messages even without the card).
Hope this helps.
