I have three different machines running Xubuntu 18.04 i386. All are affected.
After upgrade to kernel 4.15.0-48 the boot process will stop to an almost black screen with a few multi-coloured lines. Problem still persists with kernel 4.15.0-50. Everything works fine with kernel 4.15.0-47. -- 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/1827884 Title: Boot problems after upgrade to kernel 4.15.0-48 (18.04.2LTS/i386) Status in linux package in Ubuntu: Confirmed Bug description: NOTE: Boot problems on TWO different laptops after Software Updater updated to kernel 4.15.0-48 Both laptops running Ubuntu 18.04.2LTS i386/32bit with Xubuntu desktop. Both fresh installs from minimal CD in early April, originally kernel 0.4.15.0-47, both working fine. Bug report filed on THIS MACHINE: HP Compag 6710b, Intel Core2 Duo T7100 @ 1.8GHz, RAM 4GB, with Intel integrated graphics controller GM965/GL960 (with kernel command line parameter ¨video=SVIDEO-1:d¨) SYMPTOM: 4.15.0-48 requires a second ´recovery´ boot to get it up and running. Will not boot properly after a normal shutdown - screen goes funny and it hangs Does boot successfully after a hard shutdown - detects improper shutdown, loads grub menu, then boot successfully Boot problem appeared after update from kernel version 4.15.0-47 to 4.15.0-48 Problem occurs in 4.15.0-48 kernel, but not in 4.15.0-47 (which still boots normally after a normal shutdown) OTHER MACHINE: Even older!!! ASUS W1N Pentium M banias 1.7gHz, 1.5GB RAM, ATI Mobility Radeon 9600 GPU. Running with command line parameter "forcepae". SYMPTOM: Won't boot at all. Was working fine under 4.15.0-47 as originally installed, until software updater installed 4.15.0-48. Now it won't boot (hangs, black screen), and I can't even get into the grub menu to try the older kernel. More Info on what I've already tried for troubleshooting (on the HP6710b) is outlined in https://answers.launchpad.net/ubuntu/+question/680486 Happy to provide more info if needed, but I'm just an end user user and new to Linux, so will be on a learning curve at this end. (and apologies in advance if this a user problem, and not an actual bug).
