I found what I believe is a regression on my Gateway ne570 laptop. It was running
mythbuntu 14.04 LTS and ubuntu 15.04 releases quite well. But when I installed
ubuntu 16.04 LTS, I found dmesg and kern.log were filling with messages like this:
Jul 10 17:01:10 buus-ne570 kernel: [ 57.741630] ACPI Error: Method reached maximum
reentrancy limit (255) (20150818/dsmethod-341)
Jul 10 17:01:10 buus-ne570 kernel: [ 57.803775] ACPI Error: Method reached maximum
reentrancy limit (255) (20150818/dsmethod-341)
Jul 10 17:01:10 buus-ne570 kernel: [ 57.866294] ACPI Error: Method reached maximum
reentrancy limit (255) (20150818/dsmethod-341)
Jul 10 17:01:10 buus-ne570 kernel: [ 57.928403] ACPI Error: Method reached maximum
reentrancy limit (255) (20150818/dsmethod-341)
These messages would be repeated several times a second, and then pause for several
seconds, then start again. I believe they are the cause of more sluggish behavior
than with the older *Buntu releases.
I followed the instructions here:
https://wiki.ubuntu.com/Kernel/KernelBisection
which lead me to doing "git bisect" on the linux-stable kernel. The result lead me
to this commit:
# first bad commit: [02b771b64b73226052d6e731a0987db3b47281e9] ACPI / EC: Fix an
issue caused by the serialized _Qxx evaluations
commit 02b771b64b73226052d6e731a0987db3b47281e9
Author: Lv Zheng <lv.zheng@intel.com>
Date: Wed Aug 12 11:12:02 2015 +0800
ACPI / EC: Fix an issue caused by the serialized _Qxx evaluations
It is proven that Windows evaluates _Qxx handlers in a parallel way. This
patch follows this fact, splits _Qxx evaluations from the NOTIFY queue to
form a separate queue, so that _Qxx evaluations can be queued up on
different CPUs rather than being queued up on a CPU0 bound queue.
Event handling related callbacks are also renamed and sorted in this patch.

The laptop was purchased from tigerdirect. Here's link to specs:
http://www.tigerdirect.com/applications/searchtools/item-details.asp?EdpNo=8556911
The laptop appears to be a re-branded Acer Aspire E1-570:
http://www.acer.com/ac/en/SI/content/model/NX.MGUEX.001
Both have Insyde UEFI firmware. The latest version for both is v2.06 and have same
release date, 11/11/2013, according to the Acer & Gateway support web sites, although the firmware reports an Oct date.
I realize it's quite likely that the laptop's firmware is the root cause of the
problem. However, since the problem did not exist on older kernels, I hope a patch
or workaround can be identified that will allow me to make good use of this laptop.
I assume this should also be reported to bugzilla.kernel.org. It is convenient to have the ubuntu-bug command do initial data collection.

The laptop was purchased from tigerdirect. Here's link to specs:
http://www.tigerdirect.com/applications/searchtools/item-details.asp?EdpNo=8556911
The laptop appears to be a re-branded Acer Aspire E1-570:
http://www.acer.com/ac/en/SI/content/model/NX.MGUEX.001
Both have Insyde UEFI firmware. The latest version for both is v2.06 and have same release date, 11/11/2013, according to the Acer & Gateway support web sites, although the firmware reports an Oct date.
I realize it's quite likely that the laptop's firmware is the root cause of the problem. However, since the problem did not exist on older kernels, I hope a patch or workaround can be identified that will allow me to make good use of this laptop.
I assume this should also be reported to bugzilla.kernel.org. It is convenient to have the ubuntu-bug command do initial data collection.

I found what I believe is a regression on my Gateway ne570 laptop. It was running mythbuntu 14.04 LTS and ubuntu 15.04 releases quite well. But when I installed ubuntu 16.04 LTS, I found dmesg and kern.log were filling with messages like this:
Jul 10 17:01:10 buus-ne570 kernel: [ 57.741630] ACPI Error: Method reached maximum reentrancy limit (255) (20150818/dsmethod-341)

These messages would be repeated several times a second, and then pause for several seconds, then start again. I believe they are the cause of more sluggish behavior than with the older *Buntu releases.
I followed the instructions here:
https://wiki.ubuntu.com/Kernel/KernelBisection
which lead me to doing "git bisect" on the linux-stable kernel. The result lead me to this commit:
# first bad commit: [02b771b64b73226052d6e731a0987db3b47281e9] ACPI / EC: Fix an issue caused by the serialized _Qxx evaluations
commit 02b771b64b73226052d6e731a0987db3b47281e9
Author: Lv Zheng <lv.zheng@intel.com>
Date: Wed Aug 12 11:12:02 2015 +0800
ACPI / EC: Fix an issue caused by the serialized _Qxx evaluations
It is proven that Windows evaluates _Qxx handlers in a parallel way. This
patch follows this fact, splits _Qxx evaluations from the NOTIFY queue to
form a separate queue, so that _Qxx evaluations can be queued up on
different CPUs rather than being queued up on a CPU0 bound queue.
Event handling related callbacks are also renamed and sorted in this patch.

Is there more testing I should do? Starting with enabling CONFIG_ACPI_DEBUG?
Would there be value in me reverting the "first bad commit" to the latest Linux-4.4 kernel or to the latest xenial kernel to see if that helps or hurts?
Is there more info I should collect, like output from acpidump? (Something I've seen mentioned on bugzilla.kernel.org)
