umm, OK. But -mm contains six patches:
printk-boot_delay-rename-printk_delay_msec-to-loops_per_msec.patch
printk-boot_delay-rename-printk_delay_msec-to-loops_per_msec-fix.patch
printk-boot_delay-rename-printk_delay_msec-to-loops_per_msec-fix-2.patch
printk-add-printk_delay-to-make-messages-readable-for-some-scenarios.patch
printk-add-printk_delay-to-make-messages-readable-for-some-scenarios-fix.patch
printk-add-printk_delay-to-make-messages-readable-for-some-scenarios-cleanup.patch
from yourself. Are they the cause?
