I recently added a Hauppauge WinTV Nova-HD-S2 into a Linux system. I experience frequent packet loss and pci_abort errors. Each time my application detects packet loss (continuity errors actually), I get the following messages in dmesg: cx88[0]: irq mpeg [0x80000] pci_abort* cx88[0]/2-mpeg: general errors: 0x00080000 Such problems occur every few seconds. I use firmware file dvb-fe-cx24116.fw version 1.26.90.0. Since the IRQ was shared with the nVidia card and a Dektec modulator, I swapped some PCI boards. The IRQ is still shared but with another Tuner I do not use when using the S2 tuner. After swapping the PCI boards, the errors occur less frequently but still happen. Assuming that the pci_abort was due to an interrupted DMA transfer, I tried to increase the PCI latency timer of the device to 248 but this did not change anything (setpci -s 05:05 latency_timer=f8). I use the tuner with a custom application which reads the complete Transport stream. This application had worked for years using DVB-T and DVB-S tuners. I tried to reduce the application read buffer input size and it did not change anything at all. Note that my application still uses the V3 API, not the S2API. But, using DVB-S transponders, it works (except the pci_abort errors). I disabled the serial port, the parallel port and the PS/2 ports in the BIOS. It did not change anything either. Does anyone have an idea, please? Thanks a lot in advance for any help. -Thierry
I have the board working in a Ubuntu 9.10 system, log below shows no pci errors:
