Title:
Regression: NVMe "Invalid Field in Command" errors and instability on
Meteor Lake (Kingston OM8PGP41024Q-AA) starting with kernel 6.17

Status in linux package in Ubuntu:
New

Bug description:
I am reporting a kernel regression affecting NVMe behavior on recent
Intel Meteor Lake hardware.

Hardware:
- CPU: Intel Core Ultra 7 (Meteor Lake, family 6 model 189)
- SSD: Kingston OM8PGP41024Q-AA (NVMe 1.4)

Observed behavior:

Kernel 6.14:
- system stable
- no increase in NVMe error log entries

Kernel 6.16 (mainline):
- system stable
- NVMe error log entries remain constant over time

Kernel 6.17 and newer (Ubuntu HWE):
- NVMe error log entries increase during normal usage
- SMART log shows repeated errors:
"Invalid Field in Command"
- system becomes unstable after some time:
- application crashes (segfaults)
- filesystem inconsistencies

SMART excerpt:
- Media and Data Integrity Errors: 0
- Error Information Log Entries: increasing during runtime
- Error type: "Invalid Field in Command"

Important observation:
- reverting to kernel 6.16 stops the increase in error count
- system stability is restored under 6.16

Reproduction:
1. Boot kernel 6.17 or newer
2. Use system normally
3. Observe increasing NVMe error count (smartctl)
4. System instability follows

Regression window:
- Not present in 6.16
- Present in 6.17 and newer kernels

Notes:
- Disk health otherwise reports OK
- No media errors reported
- Issue appears to be NVMe driver/controller interaction rather than hardware failure

This looks like a regression in the NVMe driver or related subsystem
triggered by newer kernels on this hardware.
