Need trace and ps. "show registers" would also be nice. (We really should fix kernel page faults to go through panic(), so that they get the same --- RUN AT LEAST 'trace' AND 'ps' AND INCLUDE OUTPUT WHEN REPORTING THIS PANIC! DO NOT EVEN BOTHER REPORTING THIS WITHOUT INCLUDING THAT INFORMATION! --- message that other panics get.) One possibility is that the nameidata structure that's passed to namei() changed a few weeks ago as part of the addition of the *at() functions, so if the call to that originated from inside the loaded module then it has zero chance of working unless the package was built against a system that was on the same side of the transition as the kernel you're running. That would be consistent with the fault you show, though it could be other issues. Philip Guenther
