Yuv, if the problem is reproducible on the latest mainline kernel
available (now 3.17.1), the next step would be to fully commit bisect
the kernel in order to identify the offending commit following

Title:
[Sony VAIO SVP13215CDB] suspend/resume failure
Status in “linux” package in Ubuntu:
Incomplete
Bug description:
System worked well with Xubuntu 13.10. Installed Xubuntu 14.04LTS
from scratch. Now the system is unstable.
To reproduce:
* boot up
* close the laptop lid
* reopen the lid
* try to access files
* repeat
Usually, after closing the laptop's lid, the system will correctly go
to sleep. Sometimes the system is OK after reopening the lid, but
eventually and consistently, after a few cycles, reopening the lid
turns the screen back on but every command fails. Disks and USB keys
give buffer I/O errors, the system is unstable and I am left with no
other option than to long-press the power button and lose work.
