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

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

$ cat /sys/devices/system/cpu/cpu0/cpuidle/state*/name

```
On other TrueNAS/kernel versions the server crashes in about 2 days or less.
On TrueNAS v25.04 (kernel 6.12.15), I have:
```

I hope those information can help debugging this issue.
Here is a partial dmesg from TrueNAS v25.04 (kernel v6.12.15):
