Start-up problems

[Lee Underwood]

Not sure if this is appropriate for this list ....



I am running Ubuntu 18.04. At start-up I get these messages in my log:

===============================================================

5:37:15 PM pulseaudio: [pulseaudio] bluez5-util.c: GetManagedObjects() failed: org.freedesktop.DBus.Error.NoReply: Did not receive a reply. Possible causes include: the remote application did not send a reply, the message bus security policy blocked the reply, the reply timeout expired, or the network connection was broken.

5:36:14 PM kernel: AMD-Vi: Unable to write to IOMMU perf counter.

===============================================================

Are these items that need to be taken care of? If so, any ideas how?

Thanks,

Lee
