Question


Question for people who've installed 4.9.x on Slackware 14.2 ...

What did you do about the kernel-headers Package when you installed 4.9.x on Slackware 14.2 ?

Did you also upgrade the kernel-headers Package when you installed the new kernel Packages ?

And then what about glibc which is built against the kernel-headers ?

Thanks !

volkerdi seems to publish new kernel-headers in lockstep with new kernels, so personally I upgrade them. Monkey-see, monkey-do But I don't know of any important reason to upgrade, or NOT to upgrade. AFAIK it doesn't matter much, see below.

Because Linus is really good about keeping the "don't break userspace" rule, this is (in practice) not a big deal.

If you use an old glibc with a new kernel, there are three cases to consider. New interfaces added in the new kernel will not be available. But that doesn't matter, because there is nothing in 14.2 that uses interfaces that did not exist when 14.2 came out Old deprecated interfaces are rarely removed, there is a big fuss when this happens and Patrick's official kernel configs carefully retain compatibility if an option is provided. All other interfaces should be unchanged (apart from added and removed bugs).

I'm sorry for the typing error, I meant gcc 5.3.x and the machine in question was one old 32 bit single core.

Thanks to PROBLEMCHYLD and 55020 !

I'll take 4.9.28 and the kernel-headers for a spin this weekend when I've got time to play with it.

Confirmed.

I set up a new -current VM from a new x86 -current ISO last night. Same udivmod4 symbol issue.

I set up a new -current VM from a new x86_64 ISO this morning. The VirtualBox Guest Additions kernel modules work great.

Installed the 4.9.29 kernel and when streaming video the CPU is running considerably hotter than the maximum recommended temperature. This was not a problem with the 4.9.28 kernel.

Thanks for the report. I'm building 4.9.29 now and will be sure to check that.

EDIT: Not seeing any temperature issues here. I tried Netflix and Youtube, and if anything 4.9.29 runs slightly cooler than 4.9.25.

Heads up that there's now a new thread about the udivmod4 issue:

I'm not getting huge temperature increases with the new kernel while watching a 13 min 1080p video on youtube. htop showed my core 2 duo processors were being used about 50%, sensors showed that my temps increased 10-15 degrees Celsius. The graphics card didn't break a sweat so it must have not been used.

Well, this is interesting and a little embarrassing.
Turns out the temperature increase is not related to the kernel, but to the browser... maybe...
When it became possible to view Netflix with Firefox I stopped using Vivaldi with Widevine and it never occurred to me to re-check the CPU temperature (when using Firefox).
The other night, after upgrading to the 4.9.29, kernel I happened to notice the heat increase and assumed it was associated with the new kernel.
About an hour ago I reinstalled Widevine and Vivaldi, and connected to Netflix. The
Widevine/Vivaldi combination runs almost 20 degrees (Fahrenheit) cooler than watching the same programing with Firefox.
Any thoughts you might have as to "why" would be of interest.

Thanks.

I have observed that sometimes Firefox becomes unresponsive, but eats a lot of CPU cycles. This could be a reason.

This statement is very vague indeed, as I didn't really register in what contexts this occurs, sorry.
