Hi, Julien!

Thank you for pointing me in this direction. I compiled the current kernel
version v4.1-rc8 from source earlier, and the problem is gone there.

FWIW, when closing the laptop’s lid now the system doesn’t suspend
operation, and the following error message appears in the kernel log:

    i915 0000:00:02.0: BAR 6: [??? 0x00000000 flags 0x2] has bogus alignment

However, suspending via "systemctl suspend" works well.
