I started noticing dropped packets on the RTL8139 eth device I have in
the same box as my PVR350 a few weeks ago (Shuttle ZEN, w/ 2.53GHz
Celeron D). I don't know if it was happening pre 0.3.8 but it's likely
it's been happening for a while.
I just switched the RTL driver from using PIO to MMIO (the default is
PIO in FC3 kernel) to see if it made any difference - but no. Still
dropping packets. I also tried preempt - but again, dropped packets.
This box is only running MythTV with a hauppauge PVR350 and serial IR
blaster. I have no usb or firewire devices attached:

I haven't seen ethernet device overruns in Linux for at least a decade...
My video filestore is via NFS over 100mbit wired link.
Is the ivtv driver disabling interrupts for too long a period?
