TL;DR: First time mailing-list user. Having similar issue on 
Debian-based OS, tested different kernel version and checked the cpuidle 
values, want to share them.

Hello,

I'm having the same issue on a HPE MicroServer Gen8 (with an Intel 
E3-1220L V2 CPU) since I upgraded to kernel v6.12.15 (from v6.6.44)

Note: I am using TrueNAS SCALE, which is Debian based but has it's own 
kernel flavor.

Applying `intel_iommu=off` and/or `modprobe.blacklist=hpwdt` and/or 
`intel_idle.max_cstate=x` (where x=0-2) didn't changed anything.

On the working setup (90+ days of uptime), running TrueNAS v24.10 
(kernel 6.6.44), I have:

```
$ cat /proc/cmdline
BOOT_IMAGE=/ROOT/24.10.2.4@/boot/vmlinuz-6.6.44-production+truenas 
root=ZFS=boot-pool/ROOT/24.10.2.4 ro libata.allow_tpm=1 amd_iommu=on 
iommu=pt kvm_amd.npt=1 kvm_amd.avic=1 intel_iommu=off zfsforce=1 
nvme_core.multipath=N modprobe.blacklist=hpwdt intel_idle.max_cstate=0

$ cat /sys/devices/system/cpu/cpuidle/current_driver
acpi_idle

$ ls -l /sys/devices/system/cpu/cpu0/cpuidle/
total 0
drwxr-xr-x 2 root root 0 Jan 14 09:32 state0
drwxr-xr-x 2 root root 0 Jan 14 09:32 state1
drwxr-xr-x 3 root root 0 Jan 14 09:32 state2

$ cat /sys/devices/system/cpu/cpu0/cpuidle/state*/name
POLL
C1
C2
```

On other TrueNAS/kernel versions the server crashes in about 2 days or less.

On TrueNAS v25.04 (kernel 6.12.15), I have:

```
$ cat /proc/cmdline

On TrueNAS v25.10 (kernel 6.12.33), I have:

```
$ cat /proc/cmdline

On TrueNAS v25.10 (kernel 6.12.33) with `intel_idle.max_cstate=0`, I have:


```
$ cat /proc/cmdline

I hope those information can help debugging this issue.
