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.
