[DRBD-user] kernel-2.6.9-67.0.22.EL and drbd 0.8.4

[Michael Mansour]

Hi,

I'm trying to compile drbd 0.8.4 with the latest kernel errata released from 
Red Hat. I'm using Scientific Linux 4.6 (RHEL 4 U6) and get the problem 
below:

So I still have to stick to the kernel-2.6.9-67.0.22.EL kernel (which 
compiles drbd 0.8.4 fine).

Any ideas how I can fix this?

Thanks.

Michael.
