What is KERNEL_AUTO_BOOST_LOCK_ACQUISITION_WITH_RAISED_IRQL?
This BSOD occurs when a driver attempts to acquire a kernel auto-boost lock while operating at an elevated IRQL (Interrupt Request Level). This violates Windows kernel locking rules. The error is almost exclusively caused by a buggy third-party driver — particularly security software, antivirus kernel drivers, or gaming anti-cheat systems that hook into kernel lock primitives.
Common Causes
- Buggy antivirus kernel driver
- Gaming anti-cheat kernel driver conflict
- Outdated system driver using deprecated locking APIs
Step-by-Step Fix Guide
-
1
Uninstall recently installed security software
Running Driver Verifier (verifier.exe) in standard mode helps identify the specific misbehaving driver by stress-testing all drivers.
-
2
Update or uninstall gaming anti-cheat software
WinDbg analysis of the minidump file will show exactly which driver triggered the IRQL violation.
-
3
Check minidump in WinDbg to identify faulting driver
