Summary: PCI
Product: Drivers
Version: 2.5
KernelVersion: 2.6.26-rc2
Platform: All
OS/Version: Linux
Tree: Mainline
Status: NEW
Severity: normal
Priority: P1
Component: PCI
AssignedTo: drivers_pci at kernel-bugs.osdl.org
ReportedBy: jopadan at gmail.com
CC: jopadan at gmail.com
Latest working kernel version:
Earliest failing kernel version: 2.6.26-rc2
Distribution: Gentoo Linux
Hardware Environment:
- Gigabyte K8NNXP-940 NFORCE3-150
- Opteron 240
- Voodoo 5 PCI
- ENE CB1410 cardbus bridge
- orinoco_cs based WLAN card
Software Environment: Linux-2.6.25
Problem Description:
At PCI bus initialization I get the following error:
PCI: Failed to allocate mem resource #9:4000000 at f0000000 for 0000:01:08.0
return value -16
PCI: Failed to allocate mem resource #10:4000000 at f8000000 for 0000:01:08.0
return value -16
The cause seems to be that find_resource returns -EBUSY=-16 in
kernel/resource.c for these memory ranges.
I've added some debug output to the correspondening code for the log.
Later on another error is triggered by this one causing the WLAN PCMCIA card
firmware initialization to fail.
somehow the parent bridge and the voodoo card seem to like these memory ranges
too. I'll try an AGP graphics
card later. But I noticed these kind of errors seems to be fairly common.
Steps to reproduce:
probably just use the above setup with a PCI cardbus bridge
Attached is a dmesg and lspci -v
