*** This bug is a duplicate of bug 1838115 *** https://bugs.launchpad.net/bugs/1838115 Dima, the tracking part of this problem is a little misleading. The Xenial 4.15 HWE kernel is basically the Bionic 4.15 kernel recompiled on Xenial and we track those problems only for the Bionic series (even though he problem technically showed up in Xenial). That's why I removed the Xenial tags and references. Also, although 1838115 is newer, we marked this bug as duplicate of 1838115 because we fixed 1838115 and the changelog for that fix references that bug.

Anthony, I had that problem with fresh Lubuntu 16.04 on Toshiba Sattelite L300. I don't know why but after a while the problem disappeared.

[Bug 1827884] Re: x86: mm: early boot problem on i386 with KPTI enabled
I have been searching for this bug-report for a few weeks now, and I can confirm that I too am experiencing this bug. After updating from Ubuntu 16.04 LTS to Ubuntu 18.04 LTS, upon first boot I experienced a black screen on my laptop (HP Presario V4000 from 2014). The backlight was still on and so was the fan, though there was no hard-drive activity light. After waiting for around half an hour, I cut the power and rebooted. Upon the second boot, everything worked fine, leading me to beleive it was simply a problem after updating. The next day, I booted the laptop again and experienced the black screen bug. I soon figured out that it occured every second boot (Roughly, sometimes I would experience the bug twice in a row). I decided to try “Advanced options for Ubuntu”, and selected “Ubuntu, with Linux 4.15.0-45-generic”. This worked first try. After testing multiple times, I never got a failed boot. Unfortunately I can confirm that this bug still occurs occasionally when I select: “Ubuntu, with Linux 4.15.0-54-generic” or “Ubuntu, with Linux 4.15.0-55-generic”. I’m fine continuing with what I’m currently doing, but I need to navigate to this option upon every boot, and if a family member were to attempt to use this laptop, they would probably experience the black screen and think they broke something. I’ll wait until a fix comes out for this, until then I’ll wait and see if anthing else happens. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1827884 Title: x86: mm: early boot problem on i386 with KPTI enabled To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1827884/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
