<font face="Dialog" size="2">I'm in the process of trying to upgrade the kernel on my OCFS2 cluster from 2.6.18 to 2.6.22. I've downloaded and compiled the source for kernel 2.6.22.14 on my machines, and I've restarted each of the machines with the new kernel. Two of the machines are x86_64 (Intel core2) machines, the other one is an older Xeon/i686 machine. The cluster worked fine in 2.6.18.8. With the new kernel, the first machine is able to mount the filesystem correctly, but when the second machine goes to mount the filesystem I get the following error in the /var/log/messages file and dmesg output:</font> </p>

Once it actually started to heartbeat, but then locked hard and I had to power cycle it to get it back. Anyone have any clues on where I might go to start?
