I encountered a crash-on-boot problem with some AMD-based desktops; I got it working by adding the kernel parameter

initcall_blacklist=clocksource_done_booting

It's described in this bug report:

I have an old compaq f700 laptop that I installed SL7 on.  It ran fine
until three kernel updates ago.  All of the 327 patches cause it to
crash on boot.  I have had to blacklist the new kernels in order to get
it back up.  Is this something others have encountered?  This system I
suspect has ACPI issues since it is not supported by most OS's (windows
10 and ubuntu all fail to install and the video memory is shared and
seems to be misidentified by X.org on startup).  Any suggestions on what
might be a workaround (boot options?) or what changed in the last three
kernel patches that might cause this would be appreciated.
