Seeing some strange things with DRBD 8 and kernel.

When I try to create the file system, it locks up.

        4096000, 7962624, 11239424

Writing inode tables: 154/457

It will now sit there waiting forever.

I've seen this behaviour before with 2.6.20 and the kernel connector 
(http://www.gossamer-threads.com/lists/drbd/announce/11858). I ended up 
downgrading to and fixed my problem.

However I thought that this would have been corrected with 2.6.22 (I've 
taken a look at the kernel connector code in and appears to 
have the patch detailed in the link above).
