BE1750s (BE201D2W) — BugCheck 0x9F during hibernate power-down (Netwaw18.sys 24.30.1.1)

hdn87 — Tue, 14 Apr 2026 02:44:42 GMT

Hardware: Killer Wi-Fi 7 BE1750s 320MHz (BE201D2W), MSI laptop, Intel 16-core CPU

Running on MSI Prestige 16 AI Evo

Device name MSI
Processor Intel(R) Core(TM) Ultra 7 255H (2.00 GHz)
Installed RAM 32.0 GB (31.4 GB usable)

Driver: Netwaw18.sys 24.30.1.1 (file version 24.12030.0.1), Intel Killer Performance Suite 40.26.220

OS: Windows 11 26100.x (24H2)

Problem: System BugChecks 0x9F (DRIVER_POWER_STATE_FAILURE) every time hibernate (S4) is triggered via user/application API. The Wi-Fi miniport fails to complete its D3 power-down IRP, deadlocking in netadaptercx!NxNblDatapath::SetRxHandler → ExWaitForRundownProtectionRelease. This corrupts the hibernate image, causing cold boot fallback and full session loss.

Failure bucket: 0x9F_3_POWER_DOWN_netadaptercx!NxNblDatapath::SetRxHandler Failure hash: {361f5377-1fbe-9030-44d2-40bae0455657}

Reproduced: Twice (April 13 and 14, 2026), identical stack traces. A prior NDIS live dump (March 29) shows the same driver hanging on OID requests: LKD_0x15E_MINI_StuckOID_E020183.

Key stack frames (from minidump):

Notes:

"Allow the computer to turn off this device to save power" is already unchecked
Idle-triggered hibernate (Reason=6) succeeds; user-initiated (Reason=4) crashes — may indicate a code path difference in pre-hibernate notification handling
Workaround: Disable-NetAdapter before shutdown /hconsidered ACCEPTABLE for short term solution (~~4-6 weeks)

Minidumps attached.
