Windows 7: BSOD on Lenovo t440s

BSOD on Lenovo t440s - IRQL_GT_ZERO_AT_SYSTEM_SERVICE

Hello,

I've recently moved my Windows 7 profile to a T440 from another Lenovo T400, and shortly after the move, I received my first BSOD. Within a day, I received another at the login screen. This Please see attached, and appreciate any help/insight you can provide.

Prior to moving to the new T440, I'd been receiving the same BSOD usually after a cold start.

Attached are the DM log and SF Diag created files. Thanks for the help!

Hi,

Yes, I am. Since my post, I've removed Bitdefender AV but I'm not certain this was the culprit. Do my attached files help?

The process that was active is a service from Bitdefender :)
You can safely assume it is Bitdefender that is the culprit with this crash.

Ugggggh! I had a funny suspicion since it's not BSOD'd since I removed the app. Thank you for confirming it, it's much appreciated.

You're welcome :)

The 0x4A is now a long time known to be caused by Bitdefender. I've seen Bitdefender in 99% of the time present on the system with this particular crash.
