[NOTE: WORK-AROUND AVAILABLE]
I can reproduce ezgumol's observation with the added twist that the
wireless network goes down *immediately* upon starting 'xine'. I don't
have to go to full screen at all. It it takes is playing a movie in
xine. I ran a 'ping' in one window and xine in another and as soon as
xine started the movie the 'ping' stopped and shortly later the wireless
was reported down. Further, 'dmesg' shows the 'Radio hardware status
changed to DISABLED' message coincident with starting 'xine'.
So, there apparently *is* an interaction between the Jaunty "openchrome"
video driver and the B43 wireless driver. (The HP2133 uses a CN896 Chome
9 video chip that, by default, runs with the 'openchome' driver).
I replaced the openchrome driver with the basic 'vesa' driver by adding
'Driver "vesa"' to the device section in the file /etc/X11/xorg.conf.
This forces X to use 'vesa' instead of automatically loading
'openchrome'. For example:
Section "Device"
Identifier "Configured Video Device"
Driver "vesa"
<<<< Add this line
EndSection
(You will need to reboot for this to take affect).
Once the 2133 is running under the 'vesa' driver, the problem goes away.
I ran multiple trials with the vesa driver versus the default openchrome
driver and 'xine' always killed the wireless with 'openchrome'. 'Xine'
with the 'vesa' driver *never* killed the wireless. I can run xine in a
window, or full screen (albeit slowly), without any ill effect on
wireless. You can solve the wireless issue if you're willing to live
without openchrome video acceleration.
This is a significant point. I filed this bug because wireless started failing
when I was testing Jaunty on a machine that normally runs Intrepid without
issue. This is significant because I don't run 'openchrome' under Intrepid!
That driver was pretty immature under Intrepid so, instead, I use the VIA
proprietary driver for the Chrome 9 video chip under Intrepid. This driver
works well, and provides the best acceleration, but its not yet available for
Jaunty.
Given this data, it would probably be productive to get the OpenChrome
folks involved in trouble shooting this problem.
