Howdy,
First I tried ilw@linux.intel.com which is now dead
Then linuxwifi@intel.com, but no reply.
So I'm trying here next.
Any ideas?
Sadly before that I was on 4.4 due to bugs in the NVME ACPI suspend
support that only got fixed in 4.11, so it's a big jump, my apologies
for that.
That said, I've used this wireless driver for 1.5 years with that
firmware without issues before that (kernel 4.4).
When it works, it loads with
iwlwifi 0000:04:00.0: Falling back to user helper
iwlwifi 0000:04:00.0: loaded firmware version 19.277230.0 op_mode iwlmvm
iwlwifi 0000:04:00.0: Detected Intel(R) Dual Band Wireless AC 8260, REV=0x208
iwlwifi 0000:04:00.0: L1 Enabled - LTR Enabled
iwlwifi 0000:04:00.0: L1 Enabled - LTR Enabled
3 different ways it's failing now:
1) CPU: 3 PID: 9349 at drivers/net/wireless/intel/iwlwifi/pcie/trans.c:1913 iwl_trans_pcie_grab_nic_access+0xcc/0xe1 [iwlwifi]
Timeout waiting for hardware access (CSR_GP_CNTRL 0xffffffff)
2)

3) iwlwifi 0000:04:00.0: Refused to change power state, currently in D3
Long details below:
I noted that https://wireless.wiki.kernel.org/en/users/drivers/iwlwifi
says I should use iwlwifi-8000-ucode-16.242414.0.tgz
which only ships iwlwifi-8000C-16.ucode while I have iwlwifi-8000C-19.ucode
Either way, I just had to reboot my system as the only way for the driver
to work again. Once it's loaded, it works, but it's not ok that I have
to reboot to get it working again after a suspend/resume module
load/unload.
Is it a known problem, and is there a fix?
Before the reboot, trying to load the module, gave this:

Now, I'm getting this:
iwlwifi 0000:04:00.0: Refused to change power state, currently in D3
This is bad, I can't reboot every time I come out of sleep just for wifi
to work again.
Is there a workaround? This is bad enough that I'm about to get another
wifi card to plug into USB.

Sorry, Marc. Somehow your emails really slipped through the cracks and
I hadn't seen them before.

I kernel v4.9, we stopped supporting firmware versions smaller than 22
for the 8260. But unfortunately I made a mistake in the patch[1] when I
removed support for those firmwares and I used 17, which is the lowest
version for 7260 devices.
I have just sent out a patch[2] with a fix for that.
You can probably solve your problem by getting the latest firmware we
have released, which is version 27. You can get it from the linux-
firmware.git repository[3]. Please try that and let us know how it
goes.

Thanks. I think the other problem is that
https://wireless.wiki.kernel.org/en/users/drivers/iwlwifihttps://wireless.wiki.kernel.org/en/users/drivers/iwlwifi
says to use 'iwlwifi-8000-ucode-16.242414.0.tgz' for 4.3+ kenrels.
and strangely says "iwlwifi-8000-ucode-25.30.13.0.tgz" for 4.1+ kernels.
Unless I'm crazy, it didn't have -25 when I looked last time.
Is there a way to keep what I thought was the canonical page, up to date?
Firmware 27 seems to work, but I'm getting allocation error/warnings?

Ok, now I'm getting this error with 4.11.6 when loading the module
(after having unloaded it while on batteries, to save power):

Was broken in 4.11, still broken in 4.12. This is crippling, I'm not
running linux so that I have to reboot it to reload an intel wireless
driver :-/
I currently have:

https://www.intel.com/content/www/us/en/support/articles/000005511/network-and-i-o/wireless-networking.html
still says to install
iwlwifi-8000-ucode-25.30.13.0.tgz
which in turn installs
iwlwifi-8000C-13.ucode
while the driver looks for iwlwifi-8000C-30.ucode iwlwifi-8000C-29.ucode iwlwifi-8000C-28.ucode
before loading iwlwifi-8000C-27.ucode
so, what do I do?

Can you report a bug in https://bugzilla.kernel.org so it's easier to
track this?
The problem seems to be that the rootport is not leaving D3 for some
reason when the driver is loaded again. Do you have
CONFIG_IWLWIFI_PCIE_RTPM enabled in your .config? (you shouldn't)
In any case, better continue tracking this in bugzilla, so please
report it there and include the full dmesg output so we can better
understand what is going on.

I don't know how or why, but I seem to:
saruman:~# grep IWLWIFI /boot/config-4.12.10-amd64-preempt-sysrq-20170406
CONFIG_IWLWIFI=m
CONFIG_IWLWIFI_LEDS=y
CONFIG_IWLWIFI_OPMODE_MODULAR=y
# CONFIG_IWLWIFI_BCAST_FILTERING is not set
CONFIG_IWLWIFI_PCIE_RTPM=y
CONFIG_IWLWIFI_DEBUG=y
CONFIG_IWLWIFI_DEVICE_TRACING=y
I'll remove that, thanks.

Cool, I think that might help. If it doesn't, please report a bug in
buzilla. ;)

But a Kconfig option should never break functionality, so IMHO this
still sounds like a bug in iwlwifi.

The problem is that to get this to work, some changes need to be made
in the platform side. In this case, the rootport is not configured
properly so it won't work.
We discussed this before and that's why this option now depends on
EXPERT.

Yeah, but users or distros might accidentally enable this Kconfig
option and break the driver unintentionally. And subtle bugs like this
are even worse as the user will not realise that it's because of a new
Kconfig option.
So I guess you can't automatically detect it the platform supports RTPM,
right? Maybe there should be a module parameter which has to be set to
enable this? And at least a big fat warning to the user that RTPM is
enabled, bugs are likely and the user has to know what she's doing.

Heh, we did? I have no recollection of whatsoever about that :)

I thought this was what EXPERT was used for:
menuconfig EXPERT
bool "Configure standard kernel features (expert users)"
# Unhide debug options, to make the on-by-default options visible
select DEBUG_KERNEL
help
This option allows certain base kernel options and settings
to be disabled or tweaked. This is for specialized
environments which can tolerate a "non-standard" kernel.
Only use this if you really know what you are doing.
But it seems that it's widely used even by people/distros who don't
know what they are doing. :(
Would it be okay if we just add a printk(KERN_ERR, ...)?

I'm not sure you were involved in the discussion, but that discussion
was the reason we introduced EXPERT as a dependency.

Yeah, people seem to just blindly enable kconfig options. I don't blame
them, there are so many options and difficult to know what to choose.

I think we at least we should do that, preferably even something else to
prevent accidental use if the feature is so fragile.

I've entered bug https://bugzilla.kernel.org/show_bug.cgi?id=197341
But I'm still curious what firmware I'm supposed to use:

https://www.intel.com/content/www/us/en/support/articles/000005511/network-and-i-o/wireless-networking.html
still says to install
iwlwifi-8000-ucode-25.30.13.0.tgz
which in turn installs
iwlwifi-8000C-13.ucode
while the driver looks for iwlwifi-8000C-30.ucode iwlwifi-8000C-29.ucode iwlwifi-8000C-28.ucode
before loading iwlwifi-8000C-27.ucode
Do I have the right firmware?
loaded firmware version 27.455470.0 op_mode iwlmvm
I'm still getting
