Your question:
"so what's the result on v4.12-rc1, without "nomodeset"?"
Short answer: It does not freeze.
Detailed answer:
With v4.12-rc1, by using the default kernel arguments (i.e. without
"nomodeset"), it does not freeze. It shows the login screen on the closed
laptop, which you pointed

In answer to your question "Can you confirm v4.11 freezes but v4.12-rc1
doesn't?", I can confirm that 4.11.12 freezes. Kernel log shows "NMI
watchdog: BUG: soft lockup - CPU#3 stuck for 23s! [kworker/3:1:70]".
Below are the test details along with the corresponding kernel log
output.
@Kai-Heng
Concerning your question:
v4.12-rc1 with NOMODESET -> Successfully logged in.
v4.12-rc2 with NOMODESET -> Successfully logged in.
v4.12-rc5 without NOMODESET-> Successfully logged in.
Can I say that -rc2 has freeze but -rc5 doesn't freeze?
I would say that neither of those two kernels

I trust you commented and changed the state of the bug with good intent.
Please accept my apology for being so direct... it was a complete fail.
Both links referenced do not provide any solution. One link mentions to
alter the "acpi_osi kernel parameters" without details

do not work with kernel 4.10.0-28 either. The computer freezes just
