sysdig package builds sysdig-probe.ko for incorrect kernel version. Reproducible: Always Steps to Reproduce: 1. Kernel 4.2.2 is installed. Install version 4.2.5 and change /usr/src/linux symlink. 2. After building the new kernel, do "emerge --keep-going @module-rebuild" (rebuilds sysdig). 3. New module is placed in /lib/modules/4.2.5-gentoomelf/. 4. Reboot into new kernel. 5. Try to load the new module: Actual Results: sudo modprobe sysdig-probe sysdig_probe: version magic '4.2.2-gentoomelf SMP preempt mod_unload ' should be '4.2.5-gentoomelf SMP preempt mod_unload ' modprobe: ERROR: could not insert 'sysdig_probe': Exec format error After re-building sysdig again, the module loads correctly.
