I located the change that caused this:

ommitted By:   bouyer
Date:           Tue Feb 23 21:38:36 UTC 2010
Modified Files:
        src/sys/dev/ic: ahcisata_core.c 
Log Message:
Move ahci_channel_start() after BSY has cleared (what seems to matter
here is not touching SError while BSY is asserted). Fix random
behavior (serial console corruption/misfunction, misbehavior of USB
controllers, crasy interrupts crashing the Xen hypervisor, ...)
of Intel ESB2 controller with some brand of hitachi drives.
To generate a diff of this commit:  
cvs rdiff -u -r1.22 -r1.23 src/sys/dev/ic/ahcisata_core.c

The version 1.22 works fine.
