I replied to Roland's post before reading yours... Thanks for answering the question I asked in my reply to Roland which is to which version I should upgrade: latest 8.4 = 220.127.116.11 If these log messages can't be ignored, I suppose BAD! = bad. Should I file a bug against the Debian kernel for including a drbd module with known potentially BAD! (pun intended ;-) ) bugs or is that something you'd normally do? kind regards, Jan
