Subject: [REGRESSION][BUG 94241] 4.0-rc2: Blanks screen on hibernation but does not switch off the machine
Date: Wed, 04 Mar 2015 11:47:28 +0100 [thread overview]
Message-ID: <2102769.qaa7254DPQ@merkaba> (raw)
Also reported as:
https://bugzilla.kernel.org/show_bug.cgi?id=94241
After I had [1] with 3.18 and 3.19 upto rc7, with 4.0-rc2 I get a different
issue:
The ThinkPad T520 does not hibernate at all anymore. It blanks the screen,
has some disk accesses, but then stays there. It stays on. It even seems
to continue to have some disk accesses. But its not possible to switch on
the display anymore. I tried the usual Ctrl-Alt-F1 to switch to TTY1
thing.
Expected results:
It goes to console as I have "no_console_suspend", tells me it will
hibernate, gives out the 10% step progress report on saving the image,
completes saving the image and switches off.
I am back on 3.19-rc7 as I need the machine for work. I do not foresee
having time to bisect this at the moment. I may try with kernel 4.0-rc2
again and try to SSH into the machine from a different box. Maybe I can
still log in to it in that black screen state.
This is on Debian Sid with systemd and the following hardware and software
configuration:
