@s-illes79-gmail developers asked the end user to verify the upstream kernel, it's to identify if it's a regression or fixes have been landed. It helps when we don't know the patch or the root cause of the issue at the early stage.
We know the root cause and patch of this issue, and we also know the patch has been landed after 4.11.6. 4.10 for Ubuntu zesty and HWE kernel should be fixed in next cycle, once the Ubuntu kernel team accept the SRU patch. Thanks for your feedback and contribution. -- 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/1680904 Title: zesty unable to handle kernel NULL pointer dereference Status in linux package in Ubuntu: In Progress Status in linux-hwe package in Ubuntu: Confirmed Status in linux source package in Zesty: In Progress Status in linux-hwe source package in Zesty: Confirmed Bug description: Upgraded to zesty about a week ago. Ran into this on latest kernel. (during high load, nothing in particular seems to cause it to happen). Did not happen with previous (4.10.0.14.16) kernel. Only after update to 4.10.0.15.17, has happened about 3 times since then (or other crashes), this is the one I could capture. kern.log entries below. Let me know if you need anything else from me. Thanks!
