As requested I followed the steps in
https://wiki.ubuntu.com/DebuggingKernelSuspend.
Results are:
1. Information from sticker on computer:
Manufacurer: Toshiba
Model: Protege Z835-ST6N03
Part No: PT224U-01W00C
2. Bios is already upgraded to latest version 1.80.
3. Booted in mianline upstream kernel 3.16-rc4. Suspended with pm-trace and
awakened successfully.
cat /proc/acpi/wakeup > wakeup result is attached.
4. Resume trace result:
a) Resume succeeded, though LCD brightness controls fail as originally
reported.
b) Result of: dmesg > mesg.txt will be attached.
c) Searched dmesg.txt for "Magic number" and got:
.....
[ 0.864274] Magic number: 6:405:689
[ 0.864395] rtc_cmos 00:05: setting system clock to 2014-07-09
15:41:36 UTC (1404920496)
.....
d) Searched dmesg.txt for "hash match"" and got no lines matching search.
e) Not sure whether brightness controls failing counts as "graphics related
issue".
So will attach Xorg.0.log and Xorg.0.log.old just in case.
