Hi all!
My system is now stable for over 9 days and I believe it will stay stable.
After 2 months only having uptimes of about 4 to 5 days I think I have figured
out my problem.
In my system I have two DVB cards with double tuner which needs an additional
power cord for the tuner. If the cord is not connected you only see the PCI
Card in the system but no tuner chipset. I often had the problem, that I have
to rmmod ngene, rmmod dvb-core and then to modprobe ngene 2 times to get the
cards running.
Then in mythtv when I want to record with all four tuner I have had the problem
that only two channels are recorded from only one PCI card.
So I figured out that my power supply sometimes must have break downs under
some circumstances. So I changed the power supply and everything works fine.
So I think that the "ext4/jbd2" module is often involved because of the heavy
disk accesses that takes place.
So, now I will go back to normal system. I will install again nvidia driver and
other own build kernel modules and look if the system will stay stable again.
I will keep you informed about progress.
Manfred
