Hi,
Beginning with kernel 5.12 I started getting system hangs/freezes, particularly
when starting the Chrome browser. At least some of these are logged as a timeout.
My hardware is a NVIDIA Corporation GF116 [GeForce GTX 550 Ti] [10de:1244] (rev
a1). I tried to bisect the error, but the error does not show immediately, and I
have little confidence in the bisection. For reference, my last bad commit was
05fcc256 and my last good commit was 6fc90e18.
A typical error splat is:
