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 ? ---Mike _______________________________________________ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to "freebsd-questions-unsubscr...@freebsd.org"
