dmesg log from boot to bug

Nouveau driver seems to produce soft lockups.

The most notable effect is that some syscalls "hangs", the whole
system become
very slow and this kind f message appear in every terminals:

NMI watchdog: BUG: soft lockup - CPU#6 stuck for 23s! [kworker/6:2:324]

This seems related to power management, since adding the option runpm=0
doesn't
produce the lockups. This bug can be triggered by many things, including
running commands like lspci.

I attach the dmesg log from boot up to the bug.

Based on your acpidump for an Alienware 15 R3/0GY3V1, BIOS 1.0.8 11/12/2016
with GTX 1070, I found this in ssdt6.dsl:

        Method (PGOF, 1, Serialized)
        {
...
            If (((\_SB.GGIV (0x01030009) == Zero) || (OSYS == 0x07D9)))
            {
...
            }
            Else
            {
                LKDS (PIOF)
            }
...
        }

This is a common pattern that is known to give issues. The "LKDS" part
seems to
cause issues, so you want to force the other code path. As OSYS is 2009 (set in
DSDT), try booting with:

 acpi_osi=! acpi_osi="Windows 2009"

I'm not sure what it means, but this works around the issue as well.
