Returned to computer to find Firefox frozen, tried to kill Firefox but it turned zombie, after that system froze. Still answered ping but nothing else. Rebooted by "sysrq + b". I have swap on an LVM lv on a sata SSD. I don't run luks. ** Attachment added: "kernel.log cutout." https://bugs

Pardon the comment spam, I made a mistake, your use case is * sw -> LVM -> LUKS -> nvme so both our failure cases have an extra layer between swap and LUKS -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bu

Oh also another common thing we have is, both devices are SSDs. My LUKS containers are open with 'discard' option. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1690796 Title: Kernel bug causes hang

I don't think it's encrypted swap per se, as I also have it, I think it's additional layering. In my case: * sw -> LUKS -> sda5 = OK * swapfile -> ext4 (root fs) -> LUKS -> sda2 = problem And from what I see in your case: * sw -> LUKS -> LVM -> nvme0n1p3 = problem -- You received this bug not

Yes, I have swap on LVM, of which the PVs are on a crypted fs. So: - /dev/nvme0n1p3 --> cryptsetup(luks) --> /dev/mapper/nvme0n1p3_crypt - /dev/mapper/nvme0n1p3_crypt is the physical volume in my LVM setup - swap is a logical volume in the LVM So that would be quite a curious bug, caused by encry

I had a default swapfile as set up by the 17.04 installer. Suspecting that might be the cause I changed and made a swap partition instead. So far so good, haven't had this problem since. @baszoetekouw, am I reading your UdevDB.txt correctly, you're using a swap partition in a LUKS container? Is th

I had the same happen to me, I suppose, except the process involved was Firefox. I filed the report with Bug #1692482. Marking it as duplicate. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1690796 Ti

Unfortunately, I can't really reproduce it. Journalctl shows the bug having occurred twice since the beginnen of March, om kernel 4.10.0. I'll install the 4.12 kernel and see the coming weeks if it triggers again. Thanks! Bas. On 15-05-17 22:03, Joseph Salisbury wrote: > Do you have a way to re
