Whenever I have the qla2xxx module loaded, some kernel problem eventually occurs. Sometimes its an oops, a bug, or once, a crash. The same thing has been seen to happen on 3 different machines all with qla2200 cards in them. Here is the latest backtrace: [42151.610011] kernel BUG at drivers/scsi/scsi_transport_fc.c:3022!
