Dear all, on a quite fresh vanilla (read: GENERIC) FreeBSD 10.2-RELEASE-p14 (amd64) I get many CommVault-related warnings (ioctl sign-extension ioctl) similar to those discussed for ages related to Python (June 2010 and before). This only happens on amd64, not on the previously used i386 system, so might be 32/64bit related. It seems this is because IOC_IN is defined as 0x80000000 (integer) in /usr/include/sys/ioccom.h so could it be an internal handling problem instead of calling ioctl with a wrong int/unsigned int from external program? I only see these warnings in /var/log/messages with ffffffff8004667e but that might be unrelated. I'like to get rid of these warnings (preferably with the generic kernel). Any ideas? - I'm not a C programmer so can't really dig into this :-( Many thanks and best regards, Holger
