BSOD DUMP PACKAGE - Alienware 18 Area-51 (AA18250)
Recurring 0x1E / 0x3B / 0x135 in nt!ExpPoolTrackerChargeEntry
Windows 11 25H2, build 26100.8655
Packaged 2026-06-20

SYSTEM
  Model: Alienware 18 Area-51 AA18250
  CPU:   Intel Core Ultra 9 275HX
  RAM:   64 GB DDR5
  GPU:   NVIDIA RTX 5090 Laptop + Intel Arc iGPU
  OS:    Windows 11 Home 25H2, build 26100.8655 (KB5094135 installed 2026-06-13)

FAILURE SIGNATURE (consistent across 18+ dumps since 2026-05-01)
  Fault bucket:         AV_nt!ExpPoolTrackerChargeEntry
  WER failure hash:     6f13343d-8edf-14f9-0269-6df067c74f57
  Faulting symbol:      nt!ExpPoolTrackerChargeEntry+0x40
  Faulting instruction: lock xadd qword ptr [r14+r8], rbp
    r8 (expected to be a PoolTrackTable entry pointer) holds different invalid
    values on each crash. Different garbage each time reads as a software race on
    the global pool-tag tracker table, not a hardware bit-flip.
  Caller:               nt!ExpAllocatePoolWithTagFromNode

STOP-CODE MANIFESTATIONS (same root, different subsystem trips first)
  0x1E   KMODE_EXCEPTION_NOT_HANDLED  (P1 = 0xC0000005)
  0x3B   SYSTEM_SERVICE_EXCEPTION
  0x135  REGISTRY_FILTER_DRIVER_EXCEPTION

TRIGGERING PROCESS VARIES PER CRASH (points to the shared kernel allocator, not one driver)
  Observed: explorer.exe, svchost.exe, Registry, claude.exe, chrome.exe, PowerToys, ms-teams.exe
  Sample kd buckets from individual dumps:
    claude.exe -> AV_bindflt!BfEnumerateDirectory   (directory enum -> NTFS -> pool alloc)
    chrome.exe -> AV_nt!PpmEventAddAffinityMaskAsSubset (processor power-mgmt path)
    PowerToys  -> AV_nt!ExpPoolTrackerChargeEntry    (CmOpenKey registry -> pool alloc)
    0x135      -> AV_nt!CmpCallbackFatalFilter        (registry callback -> pool alloc)

RULED OUT
  Hardware:          Windows Memory Diagnostic (2 passes), Dell ePSA, and NVMe SMART all pass.
  Third-party drivers: Driver Verifier Special Pool + Pool Tracking on ALL 41 non-Microsoft
                     drivers (every filesystem filter included) on 2026-06-17 caught nobody
                     and still produced the same plain fault in nt.
  Defender:          real-time protection fully disabled (held across reboot) on 2026-06-20.
                     Still crashed, identical signature.
  Startup software:  PowerToys and other third-party startup apps disabled. Still crashed.
  Patch:             KB5094135 (build 26100.8655, installed 2026-06-13) did NOT resolve it.
                     Recurred with the identical hash on 6/14, 6/15, 6/16, 6/17, 6/19, 6/20.

ASK
  Escalation to the kernel / pool-allocator team referencing failure hash
  6f13343d-8edf-14f9-0269-6df067c74f57, confirmation of whether a fix is planned and in
  which build, and any supported interim mitigation. Full kernel dumps and an ETW capture
  of the pre-crash registry/file event burst are available on request.
