sys/dev/aic7xxx aic7xxx_freebsd.c
Log:
Close a race condition that doesn't really exist in -current. When
a resource shortage occurs, freeze our queue and then set the resource
shortage flag while the controller data structure is locked. The old
code did these in the wrong order potentially allowing our interrupt
handler to release the queue and clear the flag before the freeze
ever occurred.
