John Ogness a424276093 printk: fix setting first seq for consoles ... It used to be that all consoles were synchronized with respect to which message they were printing. After commit a699449bb1 ("printk: refactor and rework printing logic"), all consoles have their own @seq for tracking which message they are on. That commit also changed how the initial sequence number was chosen. Instead of choosing the next non-printed message, it chose the sequence number of the next message that will be added to the ringbuffer. That change created a possibility that a non-boot console taking over for a boot console might skip messages if the boot console was behind and did not have a chance to catch up before being unregistered. Since it is not known which boot console is the same device, flush all consoles and, if necessary, start with the message of the enabled boot console that is the furthest behind. If no boot consoles are enabled, begin with the next message that will be added to the ringbuffer. Also, since boot consoles are meant to be used at boot time, handle them the same as CON_PRINTBUFFER to ensure that no initial messages are skipped.
