I have a x86-64 Pentium (4) D machine which always worked perfectly with Linux 5.2 using the TSC as the clock source. With Linux 5.3-rc1 I can't, for the life of me, boot it with anything other than clocksource=jiffies, it completely hangs without even a backtrace. At the moment I'm at work and, for obvious reasons, I'm not able to bisect this remotely. In any case, if anyone has any idea about the cause, I'll be glad to help debugging and testing any patches. Thanks in advance, Rui
