Comment 20 for bug 1856387

Hi, for those who still suffers from this issue, it was a regression issue caused by commit f723dd269d07 "x86/timer: Skip PIT initialization on modern chipsets"), which was backported to 4.15.0-71 in bug 1851216 as a fix for some other platforms. So, please try latest mainline kernel[1] as possible as there might be yet another fix to this regression, then we may finally cherry-pick it back to 4.15 and fix hardware platforms of either group. As far as we know, this issue was still reproducible on v5.5-rc5, so you may want to try something newer than that directly.
