[mythtv-users] Spontaneous Reboot when second tuner starts recording!

[John Pierce]

Hello, I have a problem that I have had no luck with solving.  This
problem has existed since I installed my PVR 500 MCE, originally on a
Fedora 4 box, now on OpenSuSE 10.1.  The system is rock solid and
stable during continuous live tv and all other aspects of MythTV with
the one exception of watching live tv and having the second tuner
start a recording.

During live tv, if the second tuner starts a scheduled recording the
system will just spontaneously reboot.  When the system is completely
rebooted the recording will continue with the recording and to get the
complete recording I must cat together the two small pieces.

If not watching live tv, all scheduled recordings proceed normally.

I can find nothing in the logs that seem abnormal to me.

I will detail my machine and supply the output of lsusb and lspci:

Custom built:
Biostar M7VIT Pro Ver 1.1
AMD Athlon XP 2000
1 Gigabyte Memory
320 Gb Disc Space (1 maxtor, 1 seagate) IDE interface
ATI Radeon 9000 AGP (128 Mb Ram)
Aureal Semiconductor AU8810 Vortex PCI Sound Card
Linksys NC100 Fast Ethernet Card

The tuner inputs are coming in on the two composite in sets of the PVR
500 MCE, External cable stb's from comcast.  Both stb's connected to
the computer through the serial ports for channel changing capability.

Any thoughts or pointers would be greatly appreciated, this one really
has me stumped.
