[mythtv-users] kernel oops! PVR 250 on 7NIF2 -- ideas?

[Brandon Beattie]

I recommend you check your CPU and bus idle settings.  I have an AMD
(2600) and an MSI mainboard that uses the via KT400 chipset.  I receive
constant Kernel Oppses and irq bitmask cleared errors when I use the
athcool program for AMD CPU's and supported mainboards to help keep the
system cooler when the CPU and bus aren't being used.  If you are using
an AMD system, google for athcool, download it, and run 'athcool stat'
and it will tell you if some setpci commands have been run to turn CPU
and bus idling on.  The fix (for me) was to turn off the idle and I
could record shows again.  I normally would not make it more than 10-120
seconds of a recording (Using pchdtv cards) before I got those errors
and the card just stopped dumping data.
