Dear Julius,

The change may also cause some hiccups if you're using a newer version of coreboot with an older version of cbmem (or SeaBIOS or whatever else reads the console): it will not crash and it will still print the whole log, but if the log has rolled over (into "ring buffer mode") it will print lines out of order. This is unfortunately the best I can do with the way current readers are implemented. I'm of course also updating the code for cbmem so as soon as you deploy the new version it will be able to display buffers from both old and new coreboot versions correctly. (I'll send patches to align SeaBIOS and the Linux memconsole driver in the same manner as soon as the coreboot patch is approved.)
Could you please also check, if GRUB’s CBMEM console driver, and the the command cbmemc to display it need any updates?
Thanks,
Paul
