Hello,
I have an Acer Aspire ES1-520 and it allways keep with load above 1.0 .
I tried to disabled everything and only when i remove the modules ohci_pci and ohci_hcd the load goes to 0.
But i need these modules, so i can use USB.
Can anyone tell me i need to check or do to solve this?
I run the next commands and check the command dmesg -T to get more information.
modprobe -r ohci_pci
modprobe -r ohci_hcd
modprobe ohci_pci
modprob ohci_hcd
dmesg -T

Your laptop actually has some USB ports that don't support USB 2.0? That's odd...
Either way you should only have ehci_hcd, blacklisting ohci_hcd and rebooting.

Hello,
I found this link http://jfcarter.net/~jimc/hardware/acer … etup.shtml that suggest to blacklist rtsx_usb_ms .
I have done that and now when the system is idle, the load is bellow 1.
cat /etc/modprobe.d/blacklist.conf
blacklist rtsx_usb_ms
Thanks for the help.
