[Kernel-packages] [Bug 1682402] Re: Running I/O heavy operation (cp) inside terminal in X server session will lock up entire system while running it in a TTY works fine

2017-04-18 Thread Jonas Thiem
I did some more testing with upstream kernel. The upstream kernel similarly has the occasional freeze where the entire desktop stops responding or updating (while the hardware mouse cursor is usually still movable but clicking doesn't do anything), however unlike the Ubuntu 17.04 kernel it always r

I just tested the latest upstream 4.11-rc7 which works fine. I didn't test a previous version of Ubuntu, since I just switched to 17.04 from Fedora 25. ** Tags added: kernel-fixed-upstream -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to l

Some additional info: - a short self-test of the SSD has already completed without errors - there was barely any memory usage while the bug occured, so it shouldn't be an out of memory issue - iotop shows always ~5 seconds of 99% I/O usage of the "cp" command at the top with nothing notable else

Just to rule out hardware issues: smartctl --all on the SSD shows no sector reallocations, barely any media wearout, no uncorrectable error count and barely any CRC errors (9). I am just running a long self-test and will report back whether it shows any errors. -- You received this bug notificat

Public bug reported: Running I/O heavy operation (cp) inside terminal in X server session will lock up entire system while running it in a TTY works fine. I am filing this as a kernel bug because the following steps will still hang the system: 1. Open up gnome-terminal 2. Start copying a really

I got the impression from my virtual server hoster (which runs the hypervisor) that other customers don't have this issue. I was also inquiried about my use of BTRFS as a filesystem, and I also use Docker very heavily which makes heavy use of special BTRFS, DeviceMapper and Cgroup features, which

It appears as if the issue is NOT present in mainline 4.9-rc7. I will wait a few more days to be sure before marking this 'kernel-fixed- upstream', since the bug always appeared in a varying interval of 2-5 days, just to get a higher level of confidence. -- You received this bug notification beca

For what it's worth, I am now running 4.9.0-040900rc7-generic since a few minutes ago. The bug always hit me after 2-5 days but always under a week, so I can tell you in at the earliest a week that the bug is or is not in upstream with high certainty. (so around 9th of December) -- You received t

The kernel panic itself locks up the system instantly and therefore no logging to disk happens of that error. Therefore, see the attached screenshot of the qemu screen after the crash. ** Attachment added: "Screenshot of VM in Qemu after crashing" https://bugs.launchpad.net/ubuntu/+source/linu

It doesn't happen *every* time when waking up from suspend, just sometimes. I can try switching to the mainline kernel and run it for a while, and hope it happens again. However, I had exactly the same problem on Fedora 21 through multiple kernel upgrades. -- You received this bug notification b
