Another vote for this needs releasing now! Before I tracked down the cause and found this bug report I'd spent hours trying to diagnose the reason for my machines instability. I'd re- installed Ubuntu over the previous version, when that didn't work got a new hard disk and did a totally new clean install and was shocked to find the machine still freezing regularly. At this point was almost sure it was a hardware problem, even though numerous memory scans had shown up nothing.
If I hadn't managed to setup Netconsole to catch the incriminating logs and then google this report I'd have bought a whole new machine by now, and been very annoyed when I'd have found the identical problem occurred on that as well. The whole handling of this problem says to me Ubuntu simply can't be looked upon as anything other than a toy for technical experts who are prepared to get their hands dirty tracking the cause of problems like this, and prepared to put their machine on ice for a few weeks while they wait for a fix to be released. You have to understand that while the problem is annoying enough in itself for those of us who know what the problem is. For those who don't know why their machines are freezing multiple times per days it's going to be causing huge amounts of grief, wasted time and expense trying to fix and diagnose the problem. -- 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: Fix Committed Status in linux-hwe-edge package in Ubuntu: In Progress Status in linux source package in Zesty: Fix Committed Status in linux-hwe-edge source package in Zesty: Fix Committed Bug description: Randomly, khugepaged process will take 100% CPU, and I can only restart the computer to recover it.
