In the meantime, I wanted to let you know that I tried the (stable) 2.6.25.3 kernel on x86-64 and encountered the same problem, but I also tried it on an IA64 system (again with the 2.6.25.3 kernel) and did *not* encounter the problem. Not sure what this means yet, but I'll let you know as soon as I get some more information.
