https://bugzilla.novell.com/show_bug.cgi?id=227391 Summary: a lot of pci_set_power_state messages in the logs after update from 10.1 to 10.2 final Product: openSUSE 10.2 Version: Final Platform: i586 OS/Version: Other Status: NEW Severity: Normal Priority: P5 - None Component: Kernel AssignedTo: kernel-maintainers@forge.provo.novell.com ReportedBy: abittner@stud.fh-heilbronn.de QAContact: qa@suse.de hello there, after doing an upgrade from suse 10.1 to opensuse 10.2 final with the downloaded cd iso images i now get a lot of kernel messages in the logfiles also check http://lists.suse.com/archive/suse-beta-e/2006-Dec/0014.html

its a normal celeron coppermine box, nothing fancy, desktop pc, no powersaving or anything exciting needed. running runlevel3 in textmode (no vesa) doing some samba, bind, squid, and so on. i dont know if i might be right but that 01:0a.0 id seems like some pci-device id to me and lspci also displays a network-card for that id
01:0a.0 Ethernet controller: 3Com Corporation 3c905 100BaseTX [Boomerang]
but this network-card doesnt support any powersaving stuff according to -v/vv/vvv

so no power-management capabilities at all. another pci-networkcard in this box displays some power-features though. so i wonder if i am correct and why the kernel tries to change the power-state of this pci-lancard and how i could get rid of the constant logging of these messages, or even better how you guys could fix this behaviour. thanks and regards. -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug, or are watching someone who is.

You may want to try killing daemons one-by-one to see which one triggers that. Perhaps pci should not complain when it is asked to do transitions on non-power-managable hardware? Greg, do you think we want attached patch? Andreas, does attached patch fix your problem? -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug, or are watching someone who is.

https://bugzilla.novell.com/show_bug.cgi?id=227391 ------- Comment #3 from abittner@stud.fh-heilbronn.de 2006-12-14 14:58 MST ------- hi there, im kinda busy these days, sorry for the delay, and my life in linux is rather userland than the developers side ;) anyways, i suppose i need to get the source packages, some development/compile stuff too and patch that pci.c sourcefile and then compile the whole kernel or something. if there are some patches for the nic-drivers, i suppose i need to compile those too and include/replace some lines in the modules.conf file or something. anyone care to give me some basic runthrough on how to do this the best way without destroying my production system. :) im willing to help but please bear with me. cheers. -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug, or are watching someone who is.
https://bugzilla.novell.com/show_bug.cgi?id=227391 ------- Comment #4 from pavel@novell.com 2006-12-20 17:09 MST ------- Yep, you need to recompile kernel; hopefully HOWTO is somewhere on the net (kernelnewbies.org?) But I do not think you want to do that on important system. You'll not loose your data, but expect some problems... -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug, or are watching someone who is.

------- Comment #9 from abittner@stud.fh-heilbronn.de 2007-03-12 20:10 MST -------
ok nevermind, i managed to patch the current sources, if i understand the patch
correctly, that one check only moves upward inside the source (pci.c)
after rebooting with the newly compiled kernel i still get these errors:
