[lubuntu] Errors when booting - Updated form 14.04 16.04 Asus Ultrabook

Hello.
Am a Linux novice. Performed an on-line update from 14.04 to 16.04 on my laptop which is an Asus Ultrabook. It has an 1T SSD and is dual-boot with Windows 8.1 via grub. Have done the same upgrade on my Intel i7 desktop without issue. It however DOES NOT have an SSD.

During boot, there are errors reported that I cannot decipher and, I believe, has to do with Ubuntu recognizing my SSD (sd9?). It is a Corsair SSD. During boot it performs some sort of disk diag that runs for 1m 50s? Sometimes it won't boot at all and I have to do the three-finger-salute (control-alt-delete).

Have a copy of my dmsg file and have attached it... (after I looked up where to find it)

Again. It's an Asus Ultrabook S500CA w/ 12G of memory (8+4 G - limitation of hardware/motherboard?). Intel® Core™ i7-3517U CPU @ 1.90GHz × 4 Intel® Ivybridge Mobile w/ 11.6 GiB available for OS use... no graphics card; just Intel Graphics drivers using processor.

Not sure what to do or how to fix it... since I cannot decipher the errors.

Please advise via email if more data is required...

Thanks. Appreciate the help.
