SubjectTREE01 rcutorture writer stalls?
Hello, Frederic,

Are you seeing rcutorture writer stalls? Please see attached for an
example from testing, search for "Call Trace". I am running an overnight
test, which should get me some idea of frequency. My thought is to run
on the same version, but without the rcutorture.nocbs_nthreads=0 and
rcutorture.nocbs_toggle=1000 kernel boot parameters.

This sort of error can occur when grace periods are progressing, but
callback processing is not. Things do seem to recover.

Other thoughts?

Thanx, Paul
