<p>in the past I've been in the same problem, the bug thing was the kernel module designed for centos being used in RHEL or vice versa. It was solved hiring support from linbit, which provided us new non-buggy compiled kernel modules</p>

The last thing I got from RedHat when I sent them a vmcore was:<br>

"We've gone through the analysis of the cores that you have provided it looks as though the panic in both cases was from trying to dereference a NULL 'sk' pointer from the 'sock_net' function."<br>

so it sounds like we're both experiencing the same thing as this person:<br>

I can reproduce it every time I reboot one of my nodes (I am running cman/clvmd/pacemaker/gfs2 on top of DRBD). I am in the process of getting DRBD support from Linbit to actually resolve this issue, but internal politics where I work is making it take longer than I was expecting.<br>
<br>
I do have a pair of older RHEL6 (pretty much initial 6.0 release plus a couple of patches from before February) systems running DRBD happily - I did take my kernel back to an earlier release on the unstable boxes and that didn't seem to do much for me.<br>
