Failed to allocate mem resource for AGP bridge
Last modified: 2005-09-07 13:38:47 UTC
I see the line
PCI: Failed to allocate mem resource #6:10000@f0000000 for 0000:01:00.0
on boot. The nvidia binary driver does not work then.
The message does not appear with 18.104.22.168 and the nvidia driver works.
I attach dmesg and lspci output.

Can you test 2.6.13-rc5 and see if this is fixed there?
Same effect with 2.6.13-rc5

Okay, I tried all 2.6.13-rc releases. All but rc1 show the mem resource failure.
So the problem came in between rc1 and rc2.
The nVidia driver does not work with rc1 either, so I suppose this has nothing
(or not much) to do with each other. I'll try and isolate the patch that causes
Backing out this patch
removes the warning. Maybe Ivan has a clue what is going on here.
nVidia now complains it can not find the device...
There's nothing we can do if the binary nvidia driver breaks, sorry. Please
I don't care about the nV driver. The original problem is the warning issued by
the kernel. I want to know if this warning is serious and points to a hardware
support problem that needs to be resolved. Or is it rather an informational
message that does not cause any harm. Please clarify.
I'd like to say it's just informational, and can be safely ignored, but I'm not
really sure. Some machines need that patch and don't work without it. Others
(like yours and bug #4965) seem to not like it at all.
But, as you are dealing with the binary nvidia driver, there's really nothing I
can do to help out, sorry. Try asking nvidia if this is an issue or not.
Never mind, the nvidia driver issue is something else (EXPORT_SYMBOL_GPL in
sysfs). See http://bugs.gentoo.org/show_bug.cgi?id=104369
