Hello guys, I'm not sure whether everything is just correct with this bug report, because it's my first one I have to make. I have some problems with my cpu load on my HP Compaq 6510b laptop when acpi is loaded. The load is simply too high even if quite nothing is running in the backgrounf. I made some screenshots using htop to explain that more detailed. I asked already some people from Arch and they think it's a kernel bug. more information and screenshots are available here: http://forum.archlinux.de/?page=Postings;id=20;thread=12521 When I deactivate acpi by adding acpi=off to the kernel line all problems seem to be solved but that's no alternative. So if some information is missing please ask otherwise I would be very thankful if you could solve that problem. :) Thank you and greets Robert
Created attachment 21601 [details] acpidump file This acpidump might help you.
Will you please also attach the output of lspci -vxxx? Thanks.
will you please attach the following output? grep . /sys/firmware/acpi/interrupts/* thanks.
Created attachment 21653 [details] output from lspci -vxxx Once the output from lspci -vxxx
Created attachment 21654 [details] interrupts And once the output of the other command. I have to thank you for your help :)
Hi, Robert From the interrupt info in comment #5 and acpidump it seems that this is related with the pcie hotplug. Will you please enable the pci hotplug in kernel configuration and see whether the issue still exists?(ACPI Pci hotplug should be set in kernel configuration). Thanks.
At least I tried to load them via putting the modules in the rc.conf of my arch system. MODULES=(pci_hotplug acpiphp shpchp pciehp [...]) I also wrote that modules in my /etc/mkinitcpio.conf MODULES="pci_hotplug acpiphp shpchp pciehp" and then ran mkinitcpio -p kernel26 But no success..Do I have to build my own kernel?
Will you please compile the pci-hotplug as built-in module? Thanks.
Created attachment 21693 [details] custom kernel config I tried to build in the modules using this config but no advance yet. Any further suggestions? Thanks :)
Do you guys need more information? So just ask me. Regards orschiro
kristen, can you look at this issue. The GPE related to a root port is keeping fire. And this looks like a hotplug issue.
Can I help you with anything?
can you give me the outpug of 'lspci -xxxx' (make sure you have root privlige). Looks BIOS enables SCI for hotplug, but current pciehp driver can't acpi event.
Also please attach the dmesg output.
Hello Shaohua, I'm afraid but my notebook broke down last week so I'm not able to meet your request. But thank you for your continous help. Best regards
hm, ok, let's close this one
