An update to that bug report suggested checking /proc/sys/fs/protected_regular, which is now set to 2 by default on my alpha. No idea where the new setting is coming from. It's a sysctl setting that has evidently been around for a good while. Other systems I have access to that are running the same kernel have that value set to 0. So I guess the current verdict is, "works as documented". Would still like to know what changed, because it's not being touched by the kernel build process: else, the other systems running the same kernel would be exhibiting the same behavior. --Bob
