Those do seem like hardware errors on the disk. But going back to the
old kernel however should not make a difference.  Try
(/usr/ports/sysutiles/smartmontools and do a
smartctl -x /dev/ad4
and see if the drive thinks it has any errors.  Does
atacontrol cap ad4
show any differences between the two kernels ?

perhaps something new is enabled or disabled between versions like the
power management ?
