Note: "permalinks" may not be as permanent as we would like,
direct links of old sources may well be a few messages off.

Sure. That was (and is still) straight from /proc/drbd.

And this is the module info:

[root at athena]~ # modinfo drbd

The server in question has not been restarted since this (second) 
problem. It's definitely 8.3.7:

[  151.222186] ---- 2011-01-07 17:45:46 ---- up

(the date/time stamp were made by me, to make sure I had a time 
reference in the log in case of problems when testing)

Anything else I can check?

(I'm pretty certain, but not 100% sure, that the first bug (registration 
problem) was with 8.3.7. However, since the server has not been booted 
since my last mail, I'm certain the latter bug is from 8.3.7)
