-------------------------------------------+--------------------------------
When I exit Live TV (whether by switching to another tuner or by exiting
to the main menu) using a HD5000 AirStar2 ATSC card, I see the following
in dmesg:
{{{
Bad page state at free_hot_cold_page (in process 'mythfrontend', page
c161d700)

Trying to fix it up, but a reboot is needed
}}}
Curiously, despite the warning about a reboot being needed, as far as I
can tell the system (mythbackend, mythfrontend, etc.) continues to run
fine. I wouldn't have even noticed the error except that on my system
syslog sends warning messages to 'wall'. This issue does *not* occur when
stopping a recording from the HD5000.
I am using the ATrpms RPM package of 0.19 with the ATrpms Nvidia 7676
drivers on a Pentium 4 3.0GHz frontend/backend running Fedora Core 4 and
the latest 2.6.15-1831_FC4smp kernel. I previously used the 0.18.1 ATrpms
package with no such error messages.
