I've dug around a little bit and found that my version of this bug is related to the linux kernel more so than the ubuntu distribution. I had it for linux kernel 3.2 and 3.4.
I found a possible solution here <http://bugs.debian.org/cgi- bin/bugreport.cgi?bug=615110> Basically, my BIOS wasn't calling TPM_startup at the appropriate time. At bootup, TPM is active. At suspend/wake, it is no longer active. The link listed above has two files which helped me triage this bug: tpm_startup.c and 10tpm_tis. 1. Compile the first file via: gcc -o tpm_startup.c tp_startup.c 2. sudo cp tpm_startup /usr/local/bin/ 3. chmod 755 10tpm_tis 4. sudo cp 10tpm_tis /etc/pm/sleep.d/ Other people have had issues in terms of the USB ports waking up their system. So this might not work for some people. ** Bug watch added: Debian Bug tracker #615110 http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=615110 -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/991606 Title: System wakes up after few minutes on suspend To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/pm-utils/+bug/991606/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
