Richard F <lists@keynet-technology.com> reported problems detecting a Kodicom 4400R: 3.0.76 on machine A: works correctly 3.0.76 on machine B: Kodicom not detected 3.12.52 on machine B: Kodicom not detected
Created attachment 200231 [details] DMESG - Machine A - older MSI with PCIe and 2 x PCI cards SLES 11 SP3 default kernel
Created attachment 200241 [details] MODPROBE - Machine A modprobe bttv gbuffers=16 card=133,132,133,133 as recommended https://www.linuxtv.org/wiki/index.php/Kodicom_4400R
Created attachment 200251 [details] LSPCI -vvv - Machine A, after modprobing
Created attachment 200261 [details] Machine B - newer LGA1155 3.0.101 kernel (SLES 11 SP4 default) Card not recognised, no effect when modprobing
Created attachment 200271 [details] Machine B - 3.12.52 kernel Pretty much the same result as 3.0 kernel Modprobe has no effect
Created attachment 200281 [details] Machine B - adding another BT878 card (IVC-100) in adjacent slot This sends the boot process a bit crazy. NOTE also that the KMC card prevents BIOS booting when it is in this adjacent slot, regardless of other cards or OS. Makes me think the BIOS may be broken.

So given that card doesn't work at all - no boot in 1 slot, I flashed the BIOS to a previous version (C29F1P01) to check - made no difference. I have not had time to create any later kernel build to test with as yet. Please suggest any steps to diagnose further / check for broken BIOS. Thanks

Created attachment 200471 [details] Machine B - 4.4.0 Kernel Some new warnings about microcode, not sure relevant Still doesn't recognise the card when modprobe'd
Created attachment 202411 [details] Machine B - 4.4.0 Kernel with pci test patch This hasn't made bttv spring into life unfortuantely
Created attachment 202421 [details] Machine B - 4.3.3 Kernel with pci=routeirq This also hasn't helped unfortunatley
Created attachment 202871 [details] Machine A - 4.3.3 Kernel - lcpci -xxx Working

Created attachment 203811 [details] Now in an HP 8300 CMT - 4.3.3 Kernel - it works! I weakened and moved everything to an HP 8300 CMT which conferred some other advantages - and same config and kernel and the card works as advertised. Something about the Foxconn card / BIOS that made it fail.
