Hi All

As we received some feedback when use the new TBS ECP3 card sometimes have i2c error or packet loss issue . then please try like this :

1.Set your BIOS PCI-E slot configuration to Gen2

2.set the GRUB like this
/etc/default/grub:
GRUB_CMDLINE_LINUX_DEFAULT="quiet splash reboot=efi,pci pci=nomsi,noaer"

3.disable the MSI in open source driver :
linux_media/drivers/media/pci/tbsecp3/tbsecp3-core.c

//static bool enable_msi = true; //annotation this line
thanks
Andreas tips if you compile failded then you can use like this :
static bool enable_msi = false;

module_param(enable_msi, bool, 0444);
MODULE_PARM_DESC(enable_msi, "use an msi interrupt if available");

then compile the driver and install reboot your PC to load the new setting .

test again if you have any more issue please send email to our support@tbsdtv.com or you can leave message here

Thanks

Kind Regards
