Kernel panic after upgrade

[tamer]

After updating to 19.1, rebooting will cause kernel panic:


Fatal trap 12: page fault while in kenl mode

I'm running in ESXi 6.7, this issue wasn't tested on 6.5 though. Other upgrades do not cause panic (tested 18.1->18.7).

Let me know if there is anything in particular I need to check. I have downgraded to 18.7.10_4 (using a snapshot) for now.

Edit: I forgot to mention that using kernel.old after upgrade boots without issue.

Dell r415 also kernel panics and reboots after tying to upgrade it to 19.1

Managed to get into it's idrac and boot the old kernel.

Adding HP 290 G1 sff to the list of kernel panics after upgrade....
kernel.old working...

Also seeing this w/ Intel i3-8100 (Gigabyte B360M DS3H mobo).

Have the same issue here on Hyper-V 9.0 after updating via GUI.

I wanted to start a fresh installation - kernel panic!
on Dell PowerEdge R340!
No workaround helps! does anyone have a tip or any other help?

I'm running this on my Dell Poweredge R210.  Have you all made sure that your Bios and firmware are up to date?  I made sure mine where all up to date before I built the box, as I just put this together last week and seems to be running well.

bios is up2date!
it's frustrating! I'm not the only one with the kernel panic!
even under vmware there are these problems! that's a joke!

Same problem, also i3 8100 and MSI board. Downgrade now until this is fixed.

What happens when you set:

hw.ibrs_disable=1
vm.pmap.pti=0

This error is the same as what I and others have experienced in this thread

Hopefully there is a solution soon.

Edit: My particular error message is the same (Verbatim) as what Shremdog and velvet have posted.

After entering
hw.ibrs_disable = 1
vm.pmap.pti = 0
Download successful.
What you need to change so as not to constantly enter these commands.

[cguilford]

Would putting them under System -> Settings -> Tunables work?

I just upgraded my Acer Aspire AMD machine from 18.7.10 --> 19.1.1 and it threw a kernel panic.  I was able to get back up and running by choosing the old kernel at the boot menu but I don't feel like this is a good solution.

Here's a screenshot of my panic:

hw.ibrs_disable=1

Doesn't setting those bypass/disable Spectre and Meltdown mitigations?
