[Yuv <1368908@xxxxxxxxxxxxxxxxxx>]

Lucky (or unlucky) me, I intensified usage by opening and closing the lid and connecting/disconnecting the power plug and the bug was triggered with 3.17.1.  The behaviour that seems to trigger it / the last activities were:
* leave Thunderbird and Skype running to have some disk activity going
* have a Skype conversation on battery power
* close the lid
* connect the power supply
* open the lid
* check emails or do something else that causes disk access

unfortunately I did not have a web browser session running and I cannot
start a browser to copy & paste from the dmesg and any attempt to start
software results in errors.

opening a new terminal tab:
  Segmentation fault
  /usr/bin/lesspipe: 295: [: =: unexpected operation

the dmesg log is too long to manually retype from screen, some of the
suspicious message:

The machine is in an unusable state, so I will reboot it, install mainline kernel v3.14.1 (the latest one published for 13.10 / trusty) with the expectation that it does not have the bug, then prepare for a bisection

Title:
  [Sony VAIO SVP13215CDB] suspend/resume failure

Status in “linux” package in Ubuntu:
  Confirmed

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.
