Dear kernel developers,
since mainline kernel 4.18 (up to the latest mainline kernel 4.18.5) Intel Core 2 Duo processors are affected by boot stalling early in the boot process. As it is so early there is no dmesg output (or any log).
A few users in the Arch Linux community used git bisect and tracked the issue down to this the bad commit: 7197e77abcb65a71d0b21d67beb24f153a96055e clocksource: Remove kthread
Either reverting the bad commit or as a workaround using an additional kernel boot parameter "clocksource=hpet" has been successfully used to boot with Intel Core 2 processors and avoid the stalling.
clocksource= options parameters are one of "tsc", "hpet", "acpi_pm", most of the time hpet did the trick.
Additional information: Kernel 4.17.19 is unaffected by this issues, kernel 4.18 series and 4.19-rc1 are still affected.
Also there is the bug-report: https://bugzilla.kernel.org/show_bug.cgi?id=200957 and a duplicate one: https://bugzilla.kernel.org/show_bug.cgi?id=200959
Thanks for fixing this issue.
Siegfried
