I know, the subject is strange, but the truth is that the actual
problem is also strange.<br>
<br>
At work, we have a batch of Dell machines. We also, regularly, use a
certain type of PCI-express x1 card for video capture and playback.
Strangely, on those machines, if we insert the card into slot 2 of
the machine, the card is not visible to the kernel. It does not
appear on lspci, and obviously, the driver is not loaded and does
not work. Moving the card to a different slot resolves all of the
above problems. The machine's BIOS has an option to enumerate all
cards, and does see the card without a problem.<br>
<br>
The problem happens with Fedora Core 15, and happened on at least
three different machines, so we can rule out a machine failure.<br>
<br>
I am at a loss as to how to even begin to debug this problem.<span class="HOEnZb"><font color="#888888"><br>
