This is not a bug per-se. It tells you that those 2 processes have been
blocked for more than 2 minutes. Are you using qgroups? 5.9 is not a
stable kernel so you are not going to receive updates for bugs which
might be fixed/backported to stable kernels/upstream releases. 5.9.1 is
not even the latest version for 5.9 branch. Next time this issue appears
show us the output of :
echo w > /proc/sysrq-trigger
