[Kernel-packages] [Bug 1872964] Re: Reliable crash in lowlatency kernel with LXD
So in my case, my VM was configured with only 256MB of memory. This caused no problem on the normal -virtual kernel but caused all sorts of problems when I installed -lowlatency in the guest. Upgrading to 384MB solved the problem reliably here, so perhaps this is not the same thing afterall. - Sorry for the interruption -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux-signed in Ubuntu. https://bugs.launchpad.net/bugs/1872964 Title: Reliable crash in lowlatency kernel with LXD Status in linux-signed package in Ubuntu: Confirmed Bug description: Hello, I am able to crash 5.4.0-21-lowlatency running LXD.

[Kernel-packages] [Bug 1674838] Re: kernel BUG at /build/linux-7LGLH_/linux-4.10.0/include/linux/swapops.h:129
There must be a better way to do this... All of these issues seem to arise from a BUG event in swapops.h:129. That particular spot is a section that's only active, when the kernel was built with CONFIG_MIGRATION=y. So first step is probably to verify that CONFIG_MIGRATION is even enabled for the mainline kernel (the configs are not the same, I'm told). So for all we know, the bug could still be upstream. If somebody running the mainline kernel could post the output of the following command, that would be useful: cat /boot/config-$(uname -r) |grep CONFIG_MIGRATION If CONFIG_MIGRATION is enabled on mainline (CONFIG_MIGRATION=y in the output above), next step should be to check if some of the Ubuntu modifications touch in the source in any relevant places. The BUG event in swapops.h:129 seems to be hit if migration_entry_to_page() is called with an unlocked page. Grepping through the source, this function is only called from a handful of places, so it should be possible cross- reference with the Ubuntu modifications. Perhaps this will bring us closer to the problem a bit faster? -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1674838 Title: kernel BUG at /build/linux- 7LGLH_/linux-4.10.0/include/linux/swapops.h:129 Status in linux package in Ubuntu: In Progress Status in linux source package in Zesty: In Progress Bug description: Randomly, khugepaged process will take 100% CPU, and I can only restart the computer to recover it.

[Kernel-packages] [Bug 1641322] Re: frequently lost connection to nvme
FWIW, this appears to work around the issue:
Create file /etc/udev/rules.d/90-nvme-power.rules :
---
KERNEL=="nvme*[0-9]n*[0-9]", ATTRS{model}=="SAMSUNG MZSLW1T0HMLH-000L1*",
ATTR{device/power/control}="on"
---
On my system at least.
I'm sure the kernel should somehow blacklist settings that bakes certain
devices behave erratically, but until then, this appears to do the
trick. No issue in 4 days!

Okay, I've been running on 4.9-rc5 mainline all day, at work, with no issue at all. After I take my laptop home, boom! Same problem. This is likely triggered more often at home, where I'm on battery more than I am at work, causing more aggressive power savings to take place.

[Kernel-packages] [Bug 1396889] Re: [Lenovo ThinkPad T400] kexec reboot fails
I'm on a virtual machine and experiencing the same thing. The problem seems to be covered pretty well in pages mentioned in #8. My problem in more detail is trying to kexec the 3.16 kernel provided by linux-generic-lts-utopic in trusty (from original 3.13 kernel, to allow "normal" kernel updates on DigitalOcean). -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1396889 Title: [Lenovo ThinkPad T400] kexec reboot fails Status in linux package in Ubuntu: Triaged Bug description: After release upgrade to Utopic, when I reboot with kexec (simply with "reboot" command), my computer cold reboots after "Starting new kernel" (i.e. I need to get through the POST and GRUB), instead of the new kernel being loaded. Previously I didn't experience problems with Trusty. It matters which kernel I try to boot, while it doesn't matter what kernel I kexec from, and which version of kexec-tools I have. I can't boot 3.16.0-25, nor 3.18.0-031800rc6 from any installed kernels, while I can boot 3.13.0-39 from any kernels without any problems. I tried to downgrade kexec-tools from 1:2.0.7-1ubuntu2 (utopic) to 1:2.0.6-0ubuntu2.1 (trusty), but it made no difference. I have a Lenovo Thinkpad T400. I didn't experience the same on my other machines, so I suspect some hardware-dependent issue.
