This bug is awaiting verification that the kernel in -proposed solves the problem. Please test the kernel and update this bug with the results. If the problem is solved, change the tag 'verification-needed- bionic' to 'verification-done-bionic'. If the problem still exists, change the tag 'verification-needed-bionic' to 'verification-failed- bionic'.
If verification is not done by 5 working days from today, this fix will be dropped from the source code, and this bug will be closed. See https://wiki.ubuntu.com/Testing/EnableProposed for documentation how to enable and use -proposed.

This caused an regression as bug 1851216 that some systems may then hang at early, so a fix cherry picked back from v5.3-rc1. However, this fix also introduce yet another regression that some other users may hang at boot while PIT is diabled in the previous fix. [Fix] Commit 979923871f69 ("x86/timer: Don't skip PIT setup when APIC is disabled or in legacy mode") from v5.6-rc1, also backported to v5.4.19 and v5.5.3, fixes PIT setup in this case. [Test Case] Simply boot a patch kernel on systems affected and it shouldn't hang. [Regression Potential] Low. Stable patch and trivial backport. [Other Info] The same fix for bug 1851216 was also backported to Disco and Eoan, but they were then fixed with this 979923871f69 commit backported in bug 1866858 and bug 1867051, which pulls v5.4 stable patches into Disco and Eoan correspondingly, leaving B/OEM-B the only victims so far. ========== Original Bug Description ========== After the update to install kernel 4.15.0-72-generic (a bit over a week ago) my computer will not boot. On boot, all I see is the purple screen with: Loading Linux 4.15.0-72-generic ... Loading initial ramdisk ... and nothing happens. Just sits there. I've waited about 5-10 minutes on occasion but to no avail. I've checked a number of logs in /var/log but not found anything. If I go into the advanced options and select kernel 4.15.0-70-generic, the computer boots normally.
