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

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.

Machine B - lspci -vvv
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 200411 [details]
Machine B - 4.3.3 Kernel
Could not boot 4.4.0 kernel unfortunately, this is latest I can get working atm
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 202881 [details]
Machine B - 4.3.3 Kernel - lcpci -xxx
Not working
(In reply to Richard F from comment #13) > Created attachment 202871 [details] > Machine A - 4.3.3 Kernel - lcpci -xxx > > Working Sorry, this is actually 3.0.101 kernel 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.
