I'm running a AMD Threadripper 1950X system (Windows 10 22H2, Asus X399 Zenith Extreme, 128GB ECC DDR4-2400, Nvidia RTX A6000 with ECC on, AJA KONA HDMI). With the installation of a Mellanox CX3 card, I'm getting occasional hangs with no particularly obvious cause. The hangs are very severe -- not even CrashOnCtrlScroll can BSOD the system.

Drivers are the latest WinOF package, but they're for an earlier version of Windows, so could be the cause.

Anyone encounter this before and have a workaround/suggestions?

Similar setup on Linux seems to be fine, but I haven't booted this system into Linux long enough for a crash to appear.
