Hi all,

I have seen the following message in /var/log/messages file :-

PCI: Device 0000:01:00.0 not available because of resource collisions

Whenever this msg comes, the PCI card which is present in 0000:01:00.0
is not useful/accessible.
While detection of card, pci_set_master() fails.
But after reboot, that msg goes & card is working fine.

This card is a Network controller PCI-Express based card.
The above problem comes very rarely & not on all the test nodes. The
situation may be difficult to reproduce.

So, my question is, what to interpret from the above message ?
PCI bios allocates the PCI resources. So where to look to remove this error ?

TIA,
Yogeshwar

Is there something overlapping in the PCI resource allocations? Can you 
post the lspci -vv output?

Hi Robert,

Currently card is inserted in PCI slot 06:00.0 & working fine. The
above said problem is observed very few times like 2 or 3. So, i am
sending today's lspci -vv output.
The lspci -vv output follows & it is attached also: -

Well, everything seems pretty much fine here.. think we'd really need 
the lspci and dmesg output when the problem actually shows up. I'm not 
sure why the BIOS wouldn't have been able to allocate resources for the 
card only sometimes.. The only thing that seems unusual is that you 
don't often see devices with a 16MB non-prefetchable BAR (the big ones 
are usually prefetchable video RAM from a graphics card), and the 
non-prefetchable and prefetchable regions may have to go into different 
bridge windows.. it could be that is tripping up the BIOS.
