So if both PREEMPT_RCU and SELinux > were in use, we might be missing "rcu-various-fixups.patch" from: $ grep RCU .config CONFIG_CLASSIC_RCU=3Dy # CONFIG_RCU_TORTURE_TEST is not set $ grep SECU .config # CONFIG_EXT4DEV_FS_SECURITY is not set # CONFIG_SECURITY is not set # CONFIG_SECURITY_FILE_CAPABILITIES is not set I guess not. BTW the corruption I mentioned earlier was char '=F0' and it's ('p' | 0= xf0) in=20 latin2. I think it was set_=F0ending_irq IIRC.
