Now we have a problem with the support of our Fibre Channel controllers. Because the possible target IDs on a fibre channel are 0..126, we set the max_target in the ccb_pathinq structure to 127. But this causes a problem during the installation from a CD. After installing the driver with "load disk1:iir.ko" and during booting the kernel we get the message "panic: timeout table full". I found out that the error occurs during the inquiry/test unit ready commands to the possible devices (to all possible bus/id/lun combinations). With SCSI controllers the error doesn't occur because the max_target is only 16. And if the OS is installed (i.e. with the help of a SCSI controller) the error doesn't occur on the Fibre Channel controller too. I disabled all timeout stuff in our driver but no change. Any help is greatly appreciated.
