NMI IPI: Panic requested by another pcpu

Has anyone experience this pink screen?

Going by the functions reported in the stack, looks like the host has crashed in the ahci driver module during extensive logging. Do you have any logs set to verbose or debug level logging? Any other recent changes made to your environment?

Cheers,

You checked to ensure you have completely up-to-date BIOS and firmware on this server?

Hello, I was wondering if you found a resolution to this issue?  We are running VMware ESXi 6.7 on a PowerEdge T640 and it just started presenting this very same error.

I experienced the exact same issue. In my case it was caused by a faulty driver/controller/device (AHCI / DVDROM). I solved it by disabling 'vmw_ahci' and 'ahci' drivers since I didn't use the DVDROM anyway. The SSD and HDD are on a separate RAID controller, so if that's the same in your case:

esxcli system module set --enabled=false --module=vmw_ahci

esxcli system module set --enabled=false --module=ahci

and reboot the server. The servers which have the same experience are stable now.

I also wrote an article about this on my blog, feel free to read:

Thank you for this post.

After crashing 3 times in 60 minutes, the server has been stable for 24 hours now.

I have PSOD very similar to yours, however I am running an Cisco UCS blade. Did you find out anything for your PSOD? Cisco pointed me here, but I don't have any AHCI drivers installed.

I just got this same PSOD running on a UCS blade, firmware 4.04(d) and ESXi 6.7 Update 3.  Did you find anything for this?

Hi ElizabethFoster,

Your PSOD screen shows Memory Controller Read Error messages which suggest hardware problems.  If the firmware is up-to-date and supported, I would next recommend running hardware diagnostics.
