[Bug 1228406] Re: [LENOVO 3249CTO] suspend/resume failure
So, here's something funny. The suspend/resume failures started happening for me on September 20, almost exactly 3 years after I'd gotten the machine; and was reproducible with older kernels and OSes that had previously worked fine. I had joked that maybe the BIOS had a time bomb in it, or just knew its time was up because I was due for a laptop refresh, and decided to try setting the BIOS clock back to before September 20th to see if it made any difference. I set the BIOS clock back exactly 3 months, to September 2. I have now had 8 successful suspend/resumes in a row with no problems. After the third suspend/resume, I set the clock back to the current date and the problem has still not recurred. I have no idea why this actually made a difference, of course; but it seems to have done so. I guess this bug should be closed as invalid, unless you're interested in having me poke this BIOS harder, Colin. ** Changed in: linux (Ubuntu) Status: Confirmed = Invalid -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1228406 Title: [LENOVO 3249CTO] suspend/resume failure To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1228406/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
[Bug 1228406] Re: [LENOVO 3249CTO] suspend/resume failure
I did just have a suspend/resume failure, but it was the first one after many repeated test suspend/resume cycles and it was also the first time I was transporting the laptop so could have been a physical connection coming loose anyway (I thought it had suspended successfully before I put it in the bag). The other thing I notice is that, judging by the fans while the laptop is in use, the system is now also much less loaded than it was when it was having the suspend/resume problem. Given that the symptom was the fans not shutting off when suspending, followed by a power off, perhaps this says something about the root cause. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1228406 Title: [LENOVO 3249CTO] suspend/resume failure To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1228406/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

I've added a considerable amount of debug into the suspend path in the kernel. 1. Edit /etc/default/grub and set: GRUB_CMDLINE_LINUX_DEFAULT=loglevel=7 no_console_suspend 2. Download and install the kernel .debs from: http://kernel.ubuntu.com/~cking/lp-1228406/v1/ 3. Reboot 4.

It's not a matter of anything happening on resume, fwiw; it doesn't suspend correctly.

It's been another 10 days since I last posted, and I still haven't encountered this bug again. I have no idea if it was the new kernel version or the BIOS that fixed it - I updated them both within a couple of days of eachother, so I am running the latest BIOS that Christopher linked to. Of course it could also be that I'm on a lucky streak, since I've never been able to consistently replicate the bug - but before I updated the BIOS + kernel it was happening on approximately a weekly basis. I sort of doubt that the BIOS would be the issue though (but you never know), since I've had this laptop since April 2010 and I've never faced the issue while running Windows 7 (I just switched over to Ubuntu in May).

This behavior (fans spinning on suspend, power off after a minute) is consistently reproducible at least back to 3.11.0-4. I definitely did not experience this problem while 3.11.0-4 was current.

I don't remember seeing this with 3.11.0-6, but that's not worth much; it may have just not become an issue for me that was worth reporting until I was traveling (and therefore suspending/resuming more often) and noticing a pattern. FWIW, here's my history of kernel boots. It looks like I first booted 3.11.0-7 on September 13. $ last -f /var/log/wtmp.1 | grep 'system boot' reboot system boot 3.11.0-4-generic Sat Aug 31 12:15 - 09:56 (23+21:41) reboot system boot 3.11.0-4-generic Wed Aug 28 13:37 - 09:56 (26+20:18) reboot system boot 3.10.0-6-generic Thu Aug 22 12:33 - 09:56 (32+21:23) reboot system boot 3.10.0-6-generic Sat Aug 10 09:53 - 12:31 (12+02:38) $ last | grep 'system boot'reboot system boot 3.11.0-8-generic Tue Sep 24 09:23 - 09:58 (00:35) reboot system boot 3.11.0-8-generic Mon Sep 23 18:49 - 09:58 (15:09) reboot system boot 3.11.0-8-generic Sun Sep 22 13:48 - 09:58 (1+20:10) reboot system boot 3.11.0-7-generic Fri Sep 20 15:25 - 09:58 (3+18:33) reboot system boot 3.11.0-7-generic Fri Sep 20 14:16 - 09:58 (3+19:42) reboot system boot 3.11.0-7-generic Tue Sep 17 20:11 - 09:58 (6+13:47) reboot system boot 3.11.0-7-generic Sat Sep 14 13:53 - 09:58 (9+20:05) reboot system boot 3.11.0-7-generic Fri Sep 13 19:33 - 13:52 (18:19) reboot system boot 3.11.0-7-generic Fri Sep 13 11:34 - 19:32 (07:58) reboot system boot 3.11.0-4-generic Fri Sep 13 11:30 - 11:30 (00:00) reboot system boot 3.11.0-5-generic Fri Sep 13 11:30 - 11:30 (00:00) reboot system boot 3.11.0-6-generic Fri Sep 13 11:29 - 11:29 (00:00) reboot system boot 3.11.0-7-generic Fri Sep 13 11:28 - 11:28 (00:00) reboot system boot 3.11.0-7-generic Fri Sep 13 11:27 - 11:27 (00:00) -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1228406 Title: [LENOVO 3249CTO] suspend/resume failure To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1228406/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

So you don't see any suspend/resume failures anymore, but apport keeps prompting you to open bugs? ** Changed in: linux (Ubuntu) Importance: Undecided = Medium ** Changed in: linux (Ubuntu) Status: Confirmed = Incomplete -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1228406 Title: [LENOVO 3249CTO] suspend/resume failure To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1228406/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

So you don't see any suspend/resume failures anymore, but apport keeps prompting you to open bugs? No, not at all. This *is* a suspend/resume failure. ** 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/1228406 Title: [LENOVO 3249CTO] suspend/resume failure To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1228406/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
