Christopher, thank you for the helpul directions. I was not aware of the
BIOS update.  I updated the BIOS, and I also updated
<https://help.ubuntu.com/community/BiosUpdate> (the path to the EFI
partition was wrong in the initial considerations section, and I added
the SONY experience).

I will observe if anything has changed and report back.  It sometimes
take days for the bug to crash the system, depending very much on my
usage pattern.  I have been living with this bug for about a month.  I
have tested it (with the old BIOS) against mainline kernels
<http://kernel.ubuntu.com/~kernel-ppa/mainline/?C=N;O=D>.  With all
v3.17 release candidates up until rc4, the bug was still there, even
though my impression is that it triggers less often.  Before updating
the BIOS today the system had been running with kernel 3.16.2 for four
days and had not been tripped (although I am not using the laptop very
much these days, so most of the time it was just idling with the mail
client running or suspended .  Now the system is rebooted with the new
BIOS into kernel 3.17-rc4.

Thank you again for your help.

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.
