[Xen-users] Invalid sequencer interrupt with AIC79xx driver and linux-xen kernel
I have a Dell ASC-39230(B) U320 SCSI controller. If I use the linux-2.6-xen kernel I am getting an "Invalid Sequencer interrupt" and the system hangs after this. But if I use the linux-2.6-xen0 kernel it works well. Does anyone know why this is happening and how I can make it go away?
