Fwiw, I think this should be fixed by
commit 08d60e5999540110576e7c1346d486220751b7f9

printk: fix string termination for record_print_text()
Commit f0e386ee0c0b ("printk: fix buffer overflow potential for
print_text()") added string termination in record_print_text().
However it used the wrong base pointer for adding the terminator.
This led to a 0-byte being written somewhere beyond the buffer.
Use the correct base pointer when adding the terminator.

din should be rolled forward, but there's yet another regression in rc6
breaking suspend on all machines.
