ahc parity errors with RELENG_8 from tody vs. 4 weeks ago

Sun Mar 14 21:08:13 UTC 2010

Hello,

today I refreshed one -stable machine to RELENG_8 from today and now I 
see hundreds of the excerpted lines. Never seen this before. There's a 
DAT72 drive at 0:14:0.
Do I have problems with my drive or with the new kernel?
