Sorry Walter, I should have updated with info from https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1795092
the xubuntu 18.10 x86 has the same (or very similar) messages, but they stop far sooner, and xubuntu drops to busybox/initramfs with an error. I was asked by jsalisbury to do a test; which I think proves the kernel is okay. >From #1795092 bug comment #13 follows ---------------- installed lubuntu 18.04.1 on dell 755 without updates, format of /, but used my old /home (from fedora). rebooted post install, pointed sources to my ISP's ubuntu mirror (bandwidth free updates) & dist-upgrade. I added xubuntu-desktop & some of the apps missing from my modified xfce desktop. added canonical kernel ppa; changed [ppa] source to point to cosmic; update & install kernel. reboot & login (normally!) guiverc@755-lubu:~$ screenfetch -n guiverc@755-lubu OS: Ubuntu 18.04 bionic Kernel: x86_64 Linux 4.18.0-8-generic Uptime: 10m Packages: 1678 Shell: bash 4.4.19 Resolution: 1680x1050 DE: XFCE WM: Xfwm4 WM Theme: Agualemon GTK Theme: Mist [GTK2] Icon Theme: gnome Font: Sans 10 CPU: Intel Core2 Duo E6850 @ 2x 2.71GHz GPU: ATI RV515 RAM: 477MiB / 4824MiB // in #14 from same bug report I booted xubuntu 18.10 (x86) live on same dell 755; it still has [ 99.999999] ehci-pci 0000:00:1a.7:dma_direct_map_sg: overflow 0x000000016cbe60000+2048 of device mask ffffffff -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1794922 Title: lubuntu 18.10 x86 (32bit) image fails to load "ehci-pci 0000:00:a.7: dma_direct_map_sg: overflow 0x000000016e3f3000+2048 of device mask ffffffff" repeats To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1794922/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
