Re: Problem with kernel major than 4.15.x

[Gilberto Nunes <gilberto.nunes32@xxxxxxxxx>]

Hello again!

Right now, I booted my laptop with kernel

Linux version 5.2.2-050202-generic (kernel@kathleen) (gcc version 9.1.0 (Ubuntu 9.1.0-9ubuntu2)) #201907231250 SMP Tue Jul 23 12:53:21 UTC 2019

The system boot slowly, and I have a SSD Samsung, which in kernel 4.15, boot quickly.

And there's many errors in dmesg command, like you can see in this pastbin

https://paste.ubuntu.com/p/YhbjnzYYYh/

The system get stuck for 5 seconds and then the X login screen appears!

Also, I get this message:
dmesg | grep stuck
[   40.231513] watchdog: BUG: soft lockup - CPU#0 stuck for 22s! [kworker/0:1:7]
[   68.231511] watchdog: BUG: soft lockup - CPU#0 stuck for 21s! [kworker/0:1:7]
[  104.231513] watchdog: BUG: soft lockup - CPU#0 stuck for 23s! [kworker/0:0:5]
[  176.239514] watchdog: BUG: soft lockup - CPU#3 stuck for 23s! [kworker/3:3:593]

Which make the system freeze for a while and then return to normal!

Any help?

Hi there

I am usging Linux mint here 19.1.

My laptop has the following configuration:

CPU - AMD A12-9720P RADEON R7, 12 COMPUTE CORES 4C+8G

GPU - Wani [Radeon R5/R6/R7 Graphics] (amdgpu)

Network Interface card:

01:00.1 Ethernet controller: Realtek Semiconductor Co., Ltd. RTL8111/8168/8411 PCI Express Gigabit Ethernet Controller (rev 12)

When I install kernel 4.18.x or 5.x, the network doesn't work anymore...
I can loaded the modulo r8169 andr8168.

I saw enp1s0f1 as well but there's no link at all!

Even when I fixed the IP none link!

I cannot ping the network gateway or any other IP inside LAN!

Is there somebody with the same problem????

Thanks a lot.
