pci 0000:00:02.0: BAR X: address space collision on of device

[bala150985]

After searching the net I don't seem to get an appropriate answer, Could you please suggest what is going wrong ? I feel that my system is very slow.

Hi

When you say you feel your system is slow, what metrics have you checked/performed to identify that the system is slower than it should be ?

Have you checked CPU usage, memory and swap usage ? I/O usage ?

Where do you feel the system is slow ?

As for the PCI base address register collisions mentioned in dmesg, i would try to get more context.

Please post the output of

grep -m 1 -C50 collision /var/log/dmesg

Also, please use code tags when posting text from a terminal. It makes it much easier to read.

EDIT:

The specs of you PC would be useful as well.

Kind regards
