Subject: 6.16-rcX: crashing way too often on thinkpad X220

Hi!

I have had 4th or so crash with 6.16. That's not usual.

This time capslock was blinking, indicating panic. Two crashes were
like that, two were just lockups.

This time I checked logs, and nothing unusual (besides this, but..)

Digging through older logs, I get:

Jul 08 13:44:57 duo kernel: usb 1-1.2: device descriptor read/64, error -71

But I doubt any of that is related.

Any ideas? Does anyone see similar crashes?

Best regards,
