Using using printk to continue logging messages now produces multiple line logging output unless the continuations use KERN_CONT. This causes the code dump on SH do be unreadable:
[ 40.036000] Code:
[ 40.036000] 8c0128f0:
[ 40.036000] stc
[ 40.036000] r6_bank
[ 40.036000] ,
[ 40.036000] r1
[ 40.036000]
[ 40.036000] 8c0128f2:
[ 40.036000] or
[ 40.036000] r1
[ 40.036000] ,
[ 40.036000] r2
[ 40.036000]
[ 40.036000] 8c0128f4:
[ 40.036000] ldc
[ 40.036000] r2
[ 40.036000] ,
[ 40.036000] sr
[ 40.036000]
Convert the calls to printk but the first one to pr_cont. This makes the
code dump readable again.
