Maybe the title is not really meaningful, but don't know what generates this problem. After updating the system to kernel 3.13.0.59, I noticed that the network connection drops soon after restarting the system. The router simply sees is as "off", but every other command shows the adapter working fine.
Looking at the kernel messages, I noticed the following:
[ 36.451427] type=1400 audit(1438868166.228:68): apparmor="STATUS" operation="profile_replace" profile="unconfined" name="/usr/lib/cups/backend/cups-pdf" pid=3391 comm="apparmor_parser"

When these messages show up, the network adapter stops working. Apparently, an issue w/the xhci_hcd driver?!?
It works well w/3.13.0.57 and it's still broken w/3.13.0.61. Any suggestions?
Thanks much.
