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).
> sudo dmidecode -s bios-version && sudo dmidecode -s bios-release-date R1044V7 03/24/2014 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. ** Changed in: linux (Ubuntu) Status: Incomplete => Confirmed -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1368908 Title: [Sony VAIO SVP13215CDB] suspend/resume failure To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1368908/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
