[SOLVED] Dell PowerEdge R630 reboots immediately on kernel 6.17.2-2-pve (PWR2262 / CPU0704 / UEFI0078)

[msp]

Hi,
I’m experiencing an issue booting the new Proxmox kernel 6.17.2-2-pve on a Dell PowerEdge R630.
The system boots perfectly with kernel 6.14.11-4-pve, but kernel 6.17 reboots instantly before reaching a shell.

This looks like a platform-specific regression affecting Dell 13G servers (R630/R730), so I’d like to provide details and check with the Proxmox kernel maintainers.

Hardware / Firmware
Server: Dell PowerEdge R630
CPUs: Intel(R) Xeon(R) CPU E5-2660 v3
BIOS: 2.19.0

Working Kernel, Boots normally, stable: Linux pve1 6.14.11-4-pve #1 SMP PREEMPT_DYNAMIC PMX 6.14.11-4
Failing Kernel, Reboots instantly before login: 6.17.2-2-pve
No logs are written because the system resets very early.

Dell Lifecycle Controller Logs when booting 6.17, the following appear:

• PWR2262: The Intel Management Engine has reported an internal system error. "The Intel Management Engine is unable to utilize the PECI over DMI facility."
• UEFI0078: One or more Machine Check errors occurred in the previous boot.
• CPU0704: CPU 1 machine check error detected.

These errors do not appear when booting 6.14.

Since the crash happens before userspace, I cannot collect logs from 6.17. The behavior strongly suggests a PECI / ME / VT-d interaction introduced in kernel 6.17.

Could a Proxmox kernel maintainer confirm whether kernel 6.17 has known boot issues on Dell 13G platforms?
Are there recommended kernel parameters?


Happy to run any tests or provide additional info.

Thanks!

Hi, look for this: https://pve.proxmox.com/wiki/Roadmap#9.1-known-issues
and this: https://forum.proxmox.com/threads/o...est-no-subscription.173920/page-5#post-817147

in short: you must upgrade bios and/or change 2 settings in bios and everything will work without problems.

Running latest kernel (6.17.2-2) without issues on 13G Dells. Also running fine on 12G, 11G, 10G Dells too.

These 13G Dells do have the latest firmware and BIOS. UEFI, Secure Boot, X2APIC, and IOAT DMA are enabled. I do NOT have SR-IOV enabled.

Thank you very much for your replies. I can confirm that setting X2APIC, and IOAT DMA to enabled, solved the issue, now kernel 6.17.2-2 boots normally. I do NOT have Secure Boot enabled and SR-IOV is enabled.
