Unmodified 5.4 was running successfully for whole Sunday with `tx off sg off tso off`! Disabling only tso did not help, while disabling all actually avoided the timeout.

I've attached kern.log from boot 'til 5.4 got that timeout (when I did not use these off's).

About bisecting - I need to figure out how to build linux-image and linux-headers package only, to reduce that almost hour build...
