I rebuilt my 8-STABLE kernel today using ATA_CAM to use the ada driver on my Xen VPS and found that the boot will hang for 60s, apparently because a CD image hasn't been configured for the virtual CD-ROM drive? After the "run_interrupt_driven_hooks: still waiting after 60 seconds for xpt_config" message, the boot continues and the system appears to work fine.
