Problem continues with #180 and #184. Extended boot delay (3 minutes to complete) - Message " (1of2) A start job is running for /boot/efi (dk exact time delay) AND (2of2) A start job is running for Uncomplicated firewall (takes 3 minutes to complete)". Also No Sound and No WiFi.
Kernel version #176 worked but was removed by auto update. However, Version #177 seemed to stabilize and also now working properly. Have temporarily disabled auto update to preserve version #177. Can postlogs if advised which one(s) to upload. -- 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/1973167 Title: linux-image-4.15.0-177-generic freezes on the welcome screen Status in linux package in Ubuntu: Confirmed Status in linux source package in Bionic: Confirmed Bug description: == SRU Justification == [Impact] Freeze at boot. intel-lpss is trying to synchronously load idma64 module in asynchronous conext. [Fix] Let userspace load the module to avoid the deadlock. [Test] Users confirmed the proposed fix can solve the issue. [Where problems could occur] Userspace can handle modules loading just fine, so there shouldn't be any surprise. == Original Bug Report == After updating to linux-image-4.15.0-177-generic, my machine completely freezes on the Ubuntu Welcome screen, i.e. right after switching to GUI mode. The mouse pointer is frozen, the keyboard does not even respond to CAPS LOCK or NUM LOCK, pressing CTRL+ALT+F2 shows no reaction. I cannot work with my machine at this point and have to hard reset it. Selecting advanced boot options in grub and selecting the previous linux kernel 4.15.0-176 makes it work again. So this bad bug was introduced with the 4.15.0-177 kernel release. I tried removing the nvidia-driver-510 package, presumably making Ubuntu use the "nouveau" driver, and with that, I could use the welcome screen and log in, but the machine still froze shortly afterwards. So maybe this is some sort of interference with my GeForce 1080 graphics card, but it is not specific to the driver used.
