It, the 5.4.1 kernel, does seem faster, but I have no way to measure that. The boot up to the sign on prompt (init 3) is noticably faster. No doubt about it.

The most notable difference for me [with an i5-6300U] is the time taken to load the mesa drivers, which is quite obviously a lot faster, almost immediate.

From LILO password to sign-in prompt the difference is 58 seconds on 5.4.x compared to 64 seconds on 4.19.xx.

Linux 5.4.x = Kernel panic, computer freezes, nah, it does not work well with my hardware

Had to go back to 5.3.x.

to measure boot time speed install bootchart (sbo). It will give you detailed information about boot process, so if needed you will be able to detect what is lagging and possibly how to fix the issue.

Very nice tip, do you happen to know where the bootchart graph is saved?

I guess under /var/log?

yes,
/var/log

but you can specify different location by editing

/etc/bootchartd.conf

to generate png you will have to run
bootchart-render /var/log/bootchart.tgz

obviously you need write access to the folder so either move .tgz file or edit config to save tgz in your home dir

Has anyone managed to get 5.4.1 32 bit smp up and running?
A few reports of kernel panic, e.g.
https://www.linuxquestions.org/quest...86-4175665274/
https://www.linuxquestions.org/quest...ml#post6063868
https://www.linuxquestions.org/quest...ml#post6056128

I've encountered this myself with huge-smp:
Code:
[    1.881270] Kernel panic - not syncing: Attempted to kill init! exitcode=0x00000009
[    1.881453] Kernel Offset: 0x17700000 from 0x1000000 (relocation range:0xc0000000-0xf77fdfff)
[    1.881634] ---[ end Kernel panic - not syncing: Attempted to kill init! exitcode=0x00000009 ]---
32 bit non-smp works fine, though.

I've seen that Bindestreck reported kernel panic on a 64 bit system, but that must be something different.

My LTE modem doesn't work on the new kernel. I booted the one I had some time ago, 5.2.8, and it works on the older one, so it's not a hardware problem.

The old kernel shows the following in dmesg:

LTE (and GSM) modems are probably what have caused me most headaches over 10+ years with Linux. Nowadays I rarely use my own old Huawei E3276 but checked, and it still works after upgrading to the 5.4.1 kernel (using NetworkManager).

I remember a usb_modeswitch upgrade for -current a few days ago. Did you upgrade that? Might help - or not.

Well, it works with older kernels, just not with 5.4.1

Yes, I updated usb_modeswitch. I'll try to bisect the kernel when time permits.

Friendly reminder - current Slackware arm for ARM is run on 32 bit.

I wonder where we're at with 5.4.x and the ARM and especially in regards of 64 or not to 64 yet?

(Got my banana pies up to date but my orange pie is due some soldering and troubleshooting)

I was about to try my own 5.4.1 compilation, just to check if I could spot what causes the Oops & kernel panic on x86 32 bit smp:
https://www.linuxquestions.org/quest...86-4175665274/

And now 5.4.2 is already here. Anyways, I'll stick with 5.4.1 first. In the changelog of 5.4.2 I wasn't able to find anything related to the reported Oops/panic.
