+Subject: [PATCH 099/134] printk: Consider nbcon boot consoles on seq init
+Origin: https://www.kernel.org/pub/linux/kernel/projects/rt/6.6/older/patches-6.6.7-rt18.tar.xz
+
+If a non-boot console is registering and boot consoles exist, the
+consoles are flushed before being unregistered. This allows the
+non-boot console to continue where the boot console left off.
+
+If for whatever reason flushing fails, the lowest seq found from
+any of the enabled boot consoles is used. Until now con->seq was
+checked. However, if it is an nbcon boot console, the function
+nbcon_seq_read() must be used to read seq because con->seq is
+always 0.
+
+Check if it is an nbcon boot console and if so call
+nbcon_seq_read() to read seq.
