ad0: WRITE command timeout...

[Are Bryne]

Hello,

After upgrading a computer from FreeBSD 4.8-something to 4.10-RELEASE-p3, 
I'm getting lots of the following:

ad0: WRITE command timeout tag=0 serv=0 - resetting
ata0: resetting devices .. done

I cannot recall seeing these before.
Would anyone know what this implies? It's still doing an installworld in 
single user mode, so I cannot post the disk make and model yet...

And please CC me in your reply - I am not on the -questions list.

Best regards,
Are Bryne
