I had a power outage this morning and my 4.0-Stable system suddenly started generating the following messages Jun 1 09:38:55 opal /kernel: acd0: DVD-ROM <CREATIVEDVD5240E-1> at ata1-master using PIO4 Jun 1 09:38:55 opal /kernel: Mounting root from ufs:/dev/ad0s3a Jun 1 09:38:55 opal /kernel: ad0: UDMA ICRC READ ERROR blk# 0 retrying Jun 1 09:38:55 opal last message repeated 2 times Jun 1 09:38:55 opal /kernel: ad0: UDMA ICRC READ ERROR blk# 0ata0-master: WARNING: WAIT_READY active=ATA_ACTIVE_ATA Jun 1 09:38:55 opal /kernel: falling back to PIO mode Jun 1 09:38:55 opal /kernel: WARNING: / was not properly dismounted This machine had never done this before and I noticed that the reboot hadn't taken care of the dismount message. I had to manually fsck the system. A single user boot produced much nastier messages and were persistant. I rebooted three times before I did the manual fsck. The boot to single user was the third boot. The reboot after the fsck sequence produced the following boot stream cut and pasted from dmesg.
