Here's a quick update, since I may not be able to get back to this until
early next week. I was able to build the version of systemd that is in the
master branch of the GH repo, SHA: 8255430. All tests that were executed
pass under kernel 4.16.16-300. About 10 tests were skipped. The following
skipped tests seem to be of particular interest:
* test-udev
* test-boot-timestamps
I was able to insert an "assert_se(1==0)" after the line that triggered
the assertion when booting from the installer, and numerous tests fail. So
that code is at least getting exercised.
Installed the latest version of the kernel available for F28, 4.17.3-200,
and test results were the same. I am now trying to build 4.18.0-0.rc3,
since that appears to be the latest version in rawhide.
I updated to 4.18.0-0.rc3 and the problem showed up. I didn't have long to
glance at the logs, but I am seeing the systemd segfault related to udev.
This is with whatever version my F28 system had installed, not the version
I compiled from GH. So, looks like an issue in the kernel. I'll try to
extract more info from the journal when I get a chance. Are there any boot
options, etc. that would produce additional helpful info?
Thanks!
