USB Disconnect on Lenovo TS430

[darrylpaa]

I have been experiencing problems with USB disconnects with this system.
Lenovo support (IBM) recently replaced both the motherboard and processor in hopes that this might resolve the problem.
After a few days the USB disconnects started again and continue. Only reboots seem to resolve the issue.

Looking for help with this major issue.

Info: messages log showing recent disconnect and grub.conf showing kernel parameters....
