Bug#816751: linux-image-3.16.0-4-amd64: Boot hangs at ata_piix message under 3.16.x, but works with 3.2.x version graph

2016-03-28 Thread Chad House
This doesn't seem to be Debian-specific.

I tried a number of other distro's live installers on USB -- current
versions of Ubuntu, Arch, CoreOS, Fedora, Puppy, System Rescue -- and
experienced boot hangs at various points with each.

After much fiddling with ACPI kernel boot parameters, I was able to get
reliable boots using 'nolapic' -- which effectively reduced the system to
one core. I subsequently narrowed it down to working with 'nolapic_timer',
and after comparing the dmesg output of 3.2.x to 3.16.x, began to suspect
the underlying problem was related to intel_idle -- which was disabled for
the Atom N2000 family under 3.2.x, but enabled in 3.16.x ... I think this
is the commit:

http://marc.info/?l=linux-pm=139068510624936=2

In the end, I found that I could boot the 3.16 kernel with:

intel_idle.max_cstate=0

which seems to effectively disable intel_idle and fall back the ACPI idle
driver.

Cheers,

Chad


Bug#816751: linux-image-3.16.0-4-amd64: Boot hangs at ata_piix message under 3.16.x, but works with 3.2.x

Package: src:linux
Version: 3.16.7-ckt20-1+deb8u3
Severity: critical
Justification: breaks the whole system

Dear Maintainer,

This machine had been running with an up-to-date version of Wheezy for
over a year. Following a dist-upgrade to Jessie, it no longer boots
under the 3.16.x kernel, seeming to hang when loading/initializing the
ATA library. The last boot message refers to ata_piix (see below).

It boots and runs fine under the 3.2.x LTS kernel, however.
