Why did you mark the bug as incomplete?

I know 3.17.1 is the latest mainline kernel now available.  When it was
published I could not install it without interrupting the testing of
3.17-rc7.  I have not found a way to trigger the bug in less than 10
days uptime, which means that inevitably a newer mainline kernel is
released in the meantime, so if the "latest mainline kernel available"
is a mandatory condition for completeness, this bug report will never
get completed, which I doubt is a desirable state of affairs.

OK, I understand the concept of commit bisecting and while I never built
the Linux kernel from source, I did the FreeBSD kernel a few years ago
and I think it is just a matter of time and disk space.  I am willing to
try that, but need a specific pointer:

I understand that I need two starting points: the last working kernel
version and the latest possible tip of the git repo.  Problem is: the
last working kernel version I know of was the one in Ubuntu 13.10.  Can
you help me map that to a specific git revision?

Thanks,
Yuv

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.
