Comment 2 for bug 1194934

Test log attached.

At beginning I tested with
sudo fwts s3 --s3-multiple=30 --s3-min-delay=10 --s3-max-delay=15
and had following results:

3.5.0-32 (lts-quantal) PASS (30/30)
3.8.0-25-generic (lts-raring) FAIL (FAILED at 7/30)
3.8.0 (mainline ppa) FAIL (did twice, FAILED at 21/30, 16/30)
3.8.4 (mainline ppa) FAIL (FAILED at 8/30)
3.8.6 (mainline ppa) FAIL (FAILED at 21/30)
3.8.13 (mainline ppa) FAIL (FAILED at 5/30)
3.9.3 (mainline ppa) FAIL (FAILED at 9/30)
3.10.0 (mainline ppa) PASS (30/30)

When system FAIL, ALT+SYSRQ+B can't reboot the system.

After then I retested with
sudo fwts s3 --s3-multiple=30 --s3-min-delay=20 --s3-max-delay=40
on 3.9.3 kernel. (since it passed by #31).
It did pass the 30 times stress test, however after the last resume its display gone.
But ALT+SYSRQ+B can reboot the system and numlock led is still active also.
I'll have more tests tomorrow.
