SCSI device timeout

[Derkjan de Haan]

All,

Today, after a cvsup (RELENG_6) and a rebuild of kernel and world, my system 
no longer boots. It hangs on

Waiting 5 seconds for SCSI devices to settle

Booting from the previous kernel allows my system to boot again. Please let 
me know if I can do anything to diagnose further.


regards,

Derkjan de Haan
