Hi Ravineet, Any chance your kernel was compiled with CONFIG_LIVEPATCH? If so, you built a livepatch module and you'll need to manage the patch using the /sys/kernel/livepatch directory because the kpatch command-line utility doesn't know how to interact with livepatch yet. -- Josh _______________________________________________ kpatch mailing list [email protected] https://www.redhat.com/mailman/listinfo/kpatch
