[gentoo-user] Kernel 4.12.5 hard lockups, nothing in logs.

[gentoo-user] Kernel 4.12.5 hard lockups, nothing in logs.

[Bill Kenworthy]

Hi all,
	I am getting random lockups on kernel 4.12.5.

Three intel hosts (atom, early i7, i7 haswell) - its worse after a
suspend resume session.  Because these are in use Ive gone back to
4.9.34 which is stable.

I also have some VM's and an MS surface pro 4 which are stable on
4.12.5, 6 and 8) - confusing!

Is anyone else seeing this?

Neil's reply elsewhere to Ralph may have the smoking gun clue.

I'm seeing changes in 4.12 too and haven't bothered looking further as
4.11 still works for me. My external monitors and USB keyboard & mouse
on laptops stopped working with 4.12 and other silliness which I forget.

My techie spidey-sense is telling me it all smells a lot like someone
tidied up .config and things moved around, so make oldconfig got confused.

Not to mention changing the bcache device numbering - instead of
/dev/bacache0, /dev/bcache1 etc. its become /dev/bcache0, /dev/bcache16,
/dev/bcache32, ... (offset of 16)

That bit me too ...

When running make oldconfig, which I prefer because it asks me to confirm 
settings for all new modules, Alan should make sure CONFIG_USB=y is set so.  
From what I recall the oldconfig default setting is 'not set', so user input 
is required.

Unfortunately, I have no idea why Bill's hard lockups occur.

Yup, on one of my laptops I use, I have also experienced lockups, so
I've been forced to downgrade to 4.9.x. On two other machines (one of
it is my personal pc used at daily basis, the other is just a PC for
storage purposes) I didn't noticed anything like that…

Correct.

Old Intel host here. No lock-ups but I had also USB-related problems
with 4.12 till I set this (new) option in kernel config:

CONFIG_USB_PCI:
A lot of embeded system SOC (e.g. freescale T2080) have both PCI and
USB modules. But USB module is controlled by registers directly, it
have no relationship with PCI module.

When you enable the above you get the next one:

CONFIG_USB_UHCI_HCD:
The Universal Host Controller Interface is a standard by Intel for
accessing the USB hardware in the PC (which is also called the USB
host controller). If your USB host controller conforms to this
standard, you may want to say Y, but see below. All recent boards
with Intel PCI chipsets (like intel 430TX, 440FX, 440LX, 440BX,
i810, i820) conform to this standard. Also all VIA PCI chipsets
(like VIA VP2, VP3, MVP3, Apollo Pro, Apollo Pro II or Apollo Pro
133) and LEON/GRLIB SoCs with the GRUSBHC controller.

The first option's help line is a bit misleading, my system is not an
embedded one but without UHCI I don't have any USB working. In 4.11 and
earlier USB_UHCI_HCD was not tied to USB_PCI and that's why make
oldconfig messed up in my case.

I, too, did encounter problems with 4.12 (vanilla from kernel.org). I have a
PC with radeon driver and a laptop with intel graphcis. I always do make
oldconfig when building a new kernel version. But with 4.12, both those
machines stopped working, they hung at boot, I think when switching graphics
mode.

Finally I found the time and reconfigured my kernel from scratch on the
laptop, which eventually made it work again. The big PC is still waiting for
its turn and running on 4.10 for the time being.

All these things will be lost in time, like the root partition last week.
