To start with, I pushed a patch to force guru-mode modules (much more likel= y to crash on the wrong kernel version) to build with CONFIG_MODVERSIONS=3D and = thus use the older 'vermagic' module mechanism. However, further investigation is needed to decide how the version-checking mechanisms should work. --=20 You are receiving this mail because: You are the assignee for the bug.
