[Bug 1724265] Re: Unexpected memory allocation failure in hibernation snapshot (swsusp)
I am experiencing what I think is the same problem with kernel 4.17.0-996-generic. ** Attachment added: "journalctl with 2 hibernation attempts" https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1724265/+attachment/5171300/+files/journalctl.log -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1724265 Title: Unexpected memory allocation failure in hibernation snapshot (swsusp) To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1724265/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

[Bug 1724265] Re: Unexpected memory allocation failure in hibernation snapshot (swsusp)
Testing with 4.14-rc5 I can enter hybrid-sleep with low memory usage but the system hangs after blanking the screen and displaying "Snapshotting system". In this case there are no log entries for the failure, ie the journal is truncated after initiating hybrid-sleep and then disconnecting the wifi (on NetworkManager receiving a suspend signal). It seems plausible that this is the same failure mode but with different log entries because of timing/memory differences, so I am marking the issue kernel-bug-exists-upstream. At any rate *some* kernel-bug-exists- upstream. Not relevant to this issue, I think: - the default 16.04.3 apparmor settings disabled /sbin/dhclient and /usr/sbin/cups-browsed with kernel 4.14rc5 - I renamed /etc/apparmor.* and rebooted - the system log showed repeated timeout crashes in inteldrm like that attached below. ** Tags added: kernel-bug-exists-upstream ** 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/1724265 Title: Unexpected memory allocation failure in hibernation snapshot (swsusp) To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1724265/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

... except it's not a real PPA - wouldn't that have been a more natural approach? However I'll try nonetheless. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1724265 Title: Unexpected memory allocation failure in hibernation snapshot (swsusp) To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1724265/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

>Did this issue start happening after an update/upgrade? Was there a prior kernel version where you were not having this particular problem? Not as far as I know. I think this code has been the same for a few years, and as we know hibernate was explicitly disabled by default in Ubuntu because it couldn't be made to work reliably across a range of machines. >Would it be possible for you to test the latest upstream kernel? Refer to https://wiki.ubuntu.com/KernelMainlineBuilds . Please test the latest v4.14 kernel[0].

[Bug 1724265] Re: Unexpected memory allocation failure in hibernation snapshot (swsusp)
Did this issue start happening after an update/upgrade? Was there a prior kernel version where you were not having this particular problem? Would it be possible for you to test the latest upstream kernel? Refer to https://wiki.ubuntu.com/KernelMainlineBuilds . Please test the latest v4.14 kernel[0]. If this bug is fixed in the mainline kernel, please add the following tag 'kernel-fixed-upstream'. If the mainline kernel does not fix this bug, please add the tag: 'kernel-bug-exists-upstream'. Once testing of the upstream kernel is complete, please mark this bug as "Confirmed". Thanks in advance.
