I'm able to reliably reproduce it, but I haven't been able to generate a small test case (I have to reboot every time I reproduce it). FWIW, the job which reproduces it (after a few minutes) does a lot of SMP and a fair amount of MMAPing. I'm attaching a section of the syslog that could be relevant.
I'm happy to try to run one of the intermediate 4.10.0 kernels if it would help, but I don't see them in the standard repos. Do I need to add a repository to get them? (I haven't messed with the kernel for 15 years or so.) For actually getting work done, I'll try backing out to 4.8, but I can readily try other kernels if it would help to get this resolved. ** Attachment added: "This is the syslog for the time my system was hung, recovered after reboot. It also had a bunch of NULs in the syslog before the next boot started." https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1674838/+attachment/4866224/+files/syslog_slice.txt -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1674838 Title: kernel BUG at /build/linux- 7LGLH_/linux-4.10.0/include/linux/swapops.h:129 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1674838/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
