saa7164[0]: can't get MMIO memory @ 0x0 or 0x0

saa7164[0]: can't get MMIO memory @ 0x0 or 0x0

[Lyle Sigurdson]

Hi all, and thanks for all your work.  But, I'm having a problem.

Tuner card: Hauppauge! HVR-2250
Mainboard: MSNV-939
Distro: Slackware64 13.1 (kernel 2.6.33.4)

When I modprobe saa7164:
bowman kernel: saa7164[0]: can't get MMIO memory @ 0x0 or 0x0
bowman kernel: CORE saa7164[0] No more PCIe resources for subsystem: 0070:8851
bowman kernel: saa7164: probe of 0000:04:00.0 failed with	error -22

It turns out that pci_resource_start and pci_resource_len are both returning 
null.

What could be the cause of this?  Is there a solution? 

   Lyle.

Try upping your kernel's vmalloc space

1. cat /proc/meminfo | grep -i vmalloc

Observe the vmalloctotal you have and convert from kB to MB.

2. Add a vmalloc=NNN to your kernel commandline on boot.  NNN should be the number of megabytes of address space to allow.  Try 64 or 128 megabytes more than your current setting.
