Unfortunantly all the beta drivers seem to have issues working with
mcdata switches. I've tried about 10 different versions available from
qlogic's ftp and all of them give trace messages and "scheduling while
atomic" messages when detecting luns that are going through the mcdata
switch. any suggestions would be appreciated (along with whom to
contact at qlogic regarding beta driver development).
