Problems booting 4.1.6

Problems booting 4.1.6

[Peter Weilbacher]

I've only recently upgraded the kernel from 4.0.5 to 4.1.6 and
since then I cannot boot my machine any more. It basically stops
after

  Decompressing Linux... Parsing ELF... done.
  Booting the kernel.

and if I wait long enough I'll see messages like

  INFO: rcu_sched self-detected stall on CPU { 3}
        (t=60000 jiffies g=-256 c=-257 q=193)
  rcu_sched kthread starved for 50027 jiffies!

I have basically used the same kernel config since about 3.2
which I have updated mostly with |make oldconfig|. Similarly,
I have used the same lilo config to boot since then, and only
changed the version strings in the filenames.

Up to 4.0.5 this worked fine and I can continue booting with
4.0.5 (I have two lilo entries for cases like this). All this
is on an older machine (Intel Core2 Quad) with a Gentoo
installation, and the (unpatched, "vanilla") kernel is built
and packaged using the genkernel script.

I would appreciate any pointers,
   Peter.

P.S.: Here are the kernel part of the lilo config (not sure
      any more where all those options came from!) and a diff
      of the two kernel configurations:

Re: Problems booting 4.1.6

Hi Peter,


does the following patch help:

x86/idle: Restore trace_cpu_idle to mwait_idle() calls

http://marc.info/?l=linux-kernel&m=144009977312088



x86/idle: Restore trace_cpu_idle to mwait_idle() calls

Commit b253149b843f ("sched/idle/x86: Restore mwait_idle() to fix boot
hangs, to improve power savings and to improve performance") restores
mwait_idle(), but the trace_cpu_idle related calls are missing. This
causes powertop on my old desktop powered by Intel Core2 E6550 to
report zero wakeups and zero events.

Add them back to restore the proper behaviour.



Greetings,

Matt
