--- Comment #198 from bakarichar...@gmail.com ---
I think this problem has been verified because it affects many people.

[SUMMARY]
Kernels (even the newest) can't load on same Acer and Lenovo notebook types
because of this error and freezing:
https://bugzilla.kernel.org/attachment.cgi?id=276591
Tsc clocksource calibration then soft lockup

There are several workaround for this which can help to identify this.

1. noapic kernel parameter
2. ivrs_ioapic[4]=00:14.0 ivrs_ioapic[5]=00:00.2
(these are maybe the smbus and iommu controllers )
3. acpi_osi=! acpi_osi=\"Windows 2009\"
(no automatic stanby mode with this)


I can attach more recent dmesg logs and even SSDT DSDT tables if that is
needed.

I think all necessary information are available to fix this problem, so
!!!PLEASE DON'T SPAM!!! this thread from now on. It won't help.
