+Subject: [PATCH] Check CPUs online, not configured.
+
+When the number of CPUs detected is greater than the number of CPUs in
+the system, rasdaemon will crash when it receives some events.
+
+Looking deeper, we also fail to use the poll method for similar reasons
+in this case.
+
+All of this can be prevented by checking to see how many CPUs are
+currently online (sysconf(_SC_NPROCESSORS_ONLN)) instead of how many
+CPUs the current kernel was configured to support
+(sysconf(_SC_NPROCESSORS_CONF)).
+
+For the kernel side of the discussion, see https://lore.kernel.org/lkml/CAM6Wdxft33zLeeXHhmNX5jyJtfGTLiwkQSApc=10fqf+rQh9DA@mail.gmail.com/T/
