Why is the faster clocksource tsc not working and tells coreboot is broken ?
Thank you for editing my description! tsc=unstable also works.

Please the coreboot log messages for example by running `cbmem -1`. ---------------------------------------- dmesg: TSC found unstable after boot, most likely due to broken BIOS. Use 'tsc=unstable'.
