ATA problems(unlean fs) on recent cvsup

Hello list,

I've recently cvsup'd current (14th of Sep). After a build and install
world/kernel I rebooted to find some new and interesting kernel messages
about ata? MPSAFE. Well as the booting continued I notcied the machine was
going through more disk activity then usal. It was also taking alot longer
to actully start. Eventully the kernel dropped into single user mode.

It appears my filesystem is playing up for some reason. I haven't had any
power failures for random hangs/reboots.

After the recent cvsup my  /usr fs appears to be coruppt or something. In
single user mode I'm unable fix the problem with fsck. At first when I had
softupdates /usr fsck would give me messages like "UNEXPECTED SOFT UPDATE
INCONSISTENCY" I turned of softupate to see if it would help...it didn't. I
still can't fix the fs. I get output like "CANNOT WRITE BLK: xxx" and I'm
always unable to salvage blks and what not.

Anyway my dmesg is as follows:
