Hi,
When I built the
kernel-5.19.0-0.rc6.20220714git4a57a8400075.49.fc37.src.rpm
using rpmbuild, it builds without any error, but fails to boot. The
rc4 kernel with the same configuration with one exception runs fine.
The exception is the new automatic timing mitigation configuration
option. I turned it off, single user, no internet facing services, amd
cpu (as i understand it, has vulnerabilities, but fewer). So, no
complaints from the build process, but the kernel looks like it is
going to boot (the drive light comes on), and then it just stops with a
blank screen. Nothing in the journal since it fails at the start.
I'll be building the rc6 kernel with the new option enabled to see if
that fixes things, but the kernel should still run even if the
automatic mitigation is turned off. Should I open a bugzilla for this?
