X1 Extreme Centos 7.6.1810 - Kernel Panic

Brand new Laptop X1E regular IPS (no touch), latest firmware installed.

https://pcsupport.lenovo.com/se/en/products/laptops-and-netbooks/thinkpad-x-series-laptops/thinkpad-...

During install of Centos, screen inverts. Resumes and install completes. 

If closing the lid, led in capslock starts blinking, laptop is dead. powercycling only solution.

If not closing the lid - after random time cursor laggs to the unusable extent, pc more or less unusable, need to power cycle to get running again.

Anyone seen same behaviour? Resolution? Any Ideas?

According to https://access.redhat.com/ecosystem/hardware/3664211 should be ok ...

Kernel Panic on stable releases normally mean faulty hardware, but this should have been detected before shipping or?

Not sure what is causing this behavior, but there are a couple of things you need to be aware off:

 

* If you X1E runs with a BIOS version less than 1.17, you need to upgrade the BIOS.  Install 1.17 (or the current version 1.18).

 

* I could only install Linux (I use Debian) after setting the graphics mode in the BIOS to "discrete".  IMPORTANT: Do *not* change this setting if you run with a BIOS version less than 1.17.  It will brick your X1E and you need to send it in for repair (that happened to me).

 

With this setting, your installer should work fine.  If the CentOS installer refuses to cooperate, give Pop!_OS from System76 a chance.  With this distribution, everything works pretty much out of the box.

 

 

cheers,

Werner

Thanks for your reply!

 

Running latest firmware (1.18) and discrete graphics. :-( (also tried both 256 and 512 M mem)

Also running same version of Centos on a couple of x220 and t450s, where it performs as it should so it's clear that there is something in x1e that is not compatible.

Big disappointment as purchase was targeted as a centos machine. Hence why checking compatibility page.

 

Can I return and get a refund?

Re: X1 Extreme Centos 7.6.1810 - Kernel Panic

Out of curiosity I installed CentOS 7 on my X1E on a USB stick.  After the installation I experienced the same issue you explained.  It does wake up after a suspend, but it shows only a black screen and there is no way to get into the system directly on the laptop.  You can only connect to the system using a ssh connection over the network.

Anyway, I noticed that the system is uisng the nouveau graphics driver, which may not support the 1050 grahpics card.  I installed the Nvidia driver, and a first suspend/resume worked fine.  I haven't done extensive tests, but using the Nvidia driver looks promising.

 

cheers,

Werner

 

Edit:  Did just a few more tests with "suspend to RAM" and "suspend to disk" and both operations work as expected.  Although I didn't run extensive tests, I did not notice any problem.  Everything works just fine, even the Lenovo Pen Pro works with CentOS.

 

 

PS:  I am really frustrated right now.  The manufacturers of these USB sticks only tell you the read speed, like 100MB/s or 200MB/s or whatever.  What they don't tell you is that the write speed is only about 10% of the read speed.  That meant that the installation of CentOS on a USB stick took forever.......

Thanks!

 

Just performed the update of drivers. Also tried to switch over from discrete graphics, but with limited success.

Closing lid now works (even though having a funny faint sparkling noise from inside laptop). It does not enter a panic mode (caps lock blinking). Have to run some time to see if the "random" slugginess will occur. So far I have not seen it. Fingers crossed...

 

I Very Much appreciate that you tested this out!! even more on a slow usb :-)
