Hi all,

Curious if anyone has run into an issue where PBS 3.x runs fine on a Dell NX3230 but a fresh install of 4.x or upgrade won't fully boot past the 'Loading Linux 7.0.0-3-pve | Loading intial ramdisk..' screen. After the automatic reboot, iDrac also throws out a "CPU 1 machine check error detected" message. Currently using the non-subscription repos. Replicated the issue on a 2nd NX3230.

The Dell server is fully updated, latest BIOS/Firmware updates. CPU: Intel(R) Xeon(R) CPU E5-2630 v3 @ 2.40GHz. PERC H730 Mini Controller.

Attempted a few recommended GRUB updates:

linux /boot/vmlinux-7.0.0-3-pve root=/dev/mapper/pbs-root ro quiet intel_iommu=off iommu=off

but no luck so far in case anyone has any ideas, much appreciated.

You can try adding nomodeset
And removing quiet
(removing quiet won't remove the reason of the issue but more output may show some hints).

Whether the issue is related to that idrac error - I don't know.

Thanks, I tried out removing quiet and adding nomodeset and attached picture right before the server reboots with the CPU 1 Machine Check error with the updated settings.
