It's time to upgrade the Linux kernel packages of our GNU/Linux distributions once more, as renowned Linux kernel maintainer Greg Kroah-Hartman today, February 2, 2017, announced the release of Linux kernel 4.9.7.[...]

While still not marked as "longterm" on the kernel.org website, the Linux 4.9 kernel series recently become LTS (Long Term Support), which means that it will be supported with security patches for a couple of years. It also means that OS vendors need to adopt the Linux 4.9 kernel series for their distros as soon as possible. Arch Linux and Solus are already powered by Linux kernel 4.9, so make sure you update your PCs right now.[...]

If you're using a GNU/Linux distribution powered by a kernel from the Linux 4.9 series, we recommend updating to today's Linux kernel 4.9.7 release as soon as possible. It already landed for Solus users and it's coming very soon to Arch Linux and openSUSE Tumbleweed, as well as other distro

Save me looking though all that .. is that with the network card that was causing slow boots before, or did you fix that ?

[EDIT]

As this is in a public facing forum and as a moderator VinDSL's post could be misconstrued by new users as "advice" to change kernel, I'd just like to add that Team Peppermints advice is to stick with the default kernel unless you have a specific reason to change .. if you manually install a non default kernel you'll also need to manually stay on top of security patches yourself (they will no longer be automatic).

Apples n' oranges.  The (above) is my desktop machine.  I haven't installed 4.9.7 in my laptop (with the 'slow' boot times)  yet. 

Matter of fact, the new Intel 7260 wifi card just arrived, an hour or two ago.  I pulled the Broadcom card, replaced it with the Intel 7260, and decided to look for Linux drivers.  However ...

As fate would have it, I booted into '10', to make sure the new card worked.  Good thing:  it worked (including the bluetooth feature).  Bad thing:  There was a cumulative update sitting there, whatever that means, and it tied up my lappy for 45 minutes, downloading and installing the updates.  Gotta love winders   ::)

So, I'll see if the new wifi card takes care of the 'slow' boot, and soon as I get the drivers sorted.

True !

I might also add, don't install winders 10 either (mentioned above) if you're concerned about WiFi security  ...    ;D

Well, that was interesting !

I downloaded the firmware blob from Intel, went to install it, and the drivers were already sitting in ~/lib/firmware, but the card wasn't working  :-\


So, I checked it in CLI ...

Yup, working !

So, I checked wicked (WiCD).

For some reason, wicked thought the WiFi interface addy was wlp2s0b1

I removed the 'b1' and BAM !  It immediately started working.

Aren't computers fun ?   :)

Hrm...

Something doesn't seem right.  Maybe the script I'm using to generate the plot is somehow misrepresenting the values.

If you look at the column header -- the firmware and loader times are negative seconds.  The actual boot time starts at '0', right ?

If that's the case, then I'm really getting a 4 second boot on the lappy.

It *feels* like 4 seconds -- no way it's taking 10 seconds to boot this thing ...   :P

Oh, well, I'll figure it out.  I'll test the new card on the routers at work in the morning, to see if the range improved.

Yeah I had to boot Win10 the other day expecting it to take about 2 - 3 minutes .. on rebooting "Windows is preparing your updates, do not turn off your PC" (or sommat similar) .. one and a half %&^$ing hours just to shut down >:(

Whilst staring at that damn screen for ages it dawned on me they've removed the "please" .. I'd have sworn Win7 used to say "PLEASE don't turn off your PC" (or sommat similar).

Handy to know as long as it doesn't stuff things up .. but that doesn't really change my opinion of their update system ;)

To be fair, fsck is a pain, too !

My all-time favorite fsck tale: https://goo.gl/GLFwRK

Memorable quote:  "Overall, FSCK on a 1.7 TB machine appears to take about 96+/- hours to run when you've really abused it."

About on par with chkdsk /r then ;)

If you're going to do a multiple read/copy/compare/relocate on every single individual sector of a 2TB spinner it's gonna take AGES no matter what the file system or tool doing it.

at least fsck/e2fsck gives you more control.

And who said I was being fair anyway >:D

more ANGRY at the time .. and I've never had Linux decide to run fsck just to reboot >:(

Ran some tests at work today, with my infamous Intel AC 7260 card.

First impression was it worked fine on '10', but I wasn't so sure about Linux.

Later in the day, it seemed to be working ok on Linux, so I did some forensics when I got back to the abode.

I had a feeling I was missing a few pieces of the puzzle, so I D/L & installed the Intel Graphics Update Tool.  Doesn't make since that a graphic update tool would improve my wifi card, but it contained a lot of ancillary drivers that I would have needed to download and install individually anyway -- sort of like the Microsoft 'shotgun' approach, you know ?  Toss everything in, including the kitchen sink ...

Anyway, this thing is hauling azz now, wifi, video, all things Intel.  Feels every bit as fast as my desktop machine.

Wifi upload & download speeds match the CAT5 connection speeds on my desktop machine, too, so it must be working.

I'll keep tweaking things, and give it another test at work next week. 

Back OT, I installed Linux 4.9.7 on this laptop, a few hours ago.  Running without a hitch, so far.

Oh, BTW, I found out where wicked picked up the 'b1' in wlp2s0b1
