Description Chris McDermott 2006-02-09 13:35:03 UTC 
Using the aic94xx/sas_class driver from Jeff Garzik's sas-2.6-git tree, during
boot the system will (sometimes more than) periodically panic/hang due to a race
condition between device discovery of the root disk and an attempt to mount the
root file system.
