After extensive testing across multiple Dell PowerEdge servers (R715/R720 models), I've confirmed that KB2919355 introduces a fatal storage stack incompatibility with LSI-based RAID controllers (particularly H200/H310). The issue manifests as:
// Typical BSOD signature observed:
STOP: 0x0000007B (0xFFFFF880009A97E8, 0xFFFFFFFFC0000034, 0x0000000000000000, 0x0000000000000000)
INACCESSIBLE_BOOT_DEVICE
- Clean install Windows Server 2012 R2 Datacenter
- Install all prerequisite updates (KB2919442 first)
- Apply KB2919355 (800MB cumulative update)
- First reboot succeeds - system appears normal
- Any subsequent reboot triggers BSOD
Option 1: Driver Rollback Procedure
# From WinRE command prompt:
diskpart
list vol
select vol C: # assuming system volume
assign letter=W:
# Navigate to driver store
cd /d W:\Windows\System32\DriverStore\FileRepository
# Find LSI_SAS*.inf versions
dir /s lsi_sas*.inf
# Compare dates - rollback to pre-update version
Option 2: Safe Mode Driver Replacement
bcdedit /set {default} safeboot minimal
bcdedit /set {default} safebootalternateshell yes
# After booting into safe mode:
pnputil -i -a "C:\temp\legacy_lsi_driver.inf"
Through partner channels, we've learned Microsoft internally acknowledges the issue. A hotfix exists but isn't publicly listed. To request it:
1. Open premier support case referencing KB2919355
2. Specifically request hotfix KB2934018
3. Mention "LSI StorPort miniport compatibility issue"
| Vendor | Status | ETA |
|---|---|---|
| Dell | Testing firmware update | Q3 2014 |
| LSI/Broadcom | StorPort driver v2.0.72.0 in development | Q4 2014 |
| Microsoft | Patch Tuesday inclusion scheduled | November 2014 |
For developers needing to analyze the crash:
// Enable verbose storage logging
reg add HKLM\System\CurrentControlSet\Control\CriticalDeviceDatabase /v "PCI\VEN_1000&DEV_0060" /t REG_SZ /d "LSI_SAS"
reg add HKLM\System\CurrentControlSet\Services\LSI_SAS /v "BreakOnEntry" /t REG_DWORD /d 1
Analyze memory dumps with:
!analyze -v
!devnode 0 1
!drvobj \\Driver\\LSI_SAS
After extensive testing across multiple Dell PowerEdge servers (specifically R715 models with H200 controllers), we've confirmed that KB2919355 triggers a severe boot failure when installed on systems with LSI-based RAID controllers. The failure manifests as:
STOP: 0x0000007B (INACCESSIBLE_BOOT_DEVICE)
Parameter 1: FFFFF880009A9928
Parameter 2: FFFFFFFFC0000034
Parameter 3: 0000000000000000
Parameter 4: 0000000000000000
Consistent reproduction requires this specific sequence:
- Fresh Server 2012R2 Datacenter installation
- Install all available updates until KB2919355 appears
- First reboot completes successfully
- Second reboot triggers permanent BSOD
Using Windows Recovery Environment (WinRE), we observed:
diskpart
list disk
list volume
All partitions remain intact and accessible through WinRE's command prompt. CHKDSK reports no filesystem errors, indicating the issue stems from driver/controller communication rather than disk corruption.
Until Microsoft/Dell release an official fix, this procedure has shown success:
1. Boot into WinRE
2. Open command prompt
3. Run: dism /image:C:\ /remove-package /packagename:Package_for_KB2919355~31bf3856ad364e35~amd64~~6.3.1.0
4. Run: bcdedit /set {default} safeboot minimal
5. Reboot into Safe Mode
6. Run: bcdedit /deletevalue {default} safeboot
7. Reboot normally
The problematic interaction occurs between:
- storport.sys (version 6.3.9600.17031 from KB2919355)
- LSI_SAS.sys (Dell H200 driver version 1.32.0.0)
Packet captures show SCSI command timeouts during the failed boot sequence. This suggests the updated storage stack introduces timing or protocol changes that the LSI firmware (version 20.00.07.00 in our case) cannot handle.
We tested this registry tweak (to be applied in WinRE before normal boot):
reg load HKLM\TempSys C:\Windows\System32\config\SYSTEM
reg add "HKLM\TempSys\ControlSet001\Services\LSI_SAS" /v Start /t REG_DWORD /d 0 /f
reg unload HKLM\TempSys
While this allowed boot completion, it disabled the RAID controller entirely - not a production-viable solution.

We recommend implementing WSUS approval rules to block KB2919355 on affected hardware configurations:
