After many attempts at installation, several posts to the mail lists and consultation with any individual that I could think of to solve my problem I am still stuck with no solution. Upon install of the generic kernel (i.e. initial install) the installation process hangs on detection of the SCSI devices. The software detects the presence of the Adaptec 2940UW (AIC 7880?) on the correct PCI slot and interrupt. The kernel then provides the message "Waiting for scsi devices to settle" (Which I believe from looking at the source for 2.2.2 should be around 5 seconds) The "settling period" extends to almost 30 seconds at which point a timeout is reported, an error is buffered, and then the detection is started over again with the next SCSI ID. As possible solutions to this problem we have checked termination on all cables, removed each of the scsi drives or a series of the drives (because we are using both Wide and narrow connectors on the UW we thought this might have been a source of conflict. In fact even if there are NO devices attatched and we boot from floppy we recieve a "board not responding" message and the above error. This would seemingly eliminate problems with termination drives, cable length etc. As for settings on the SCSI card we have tried lowering the throughput rate, enabling and disabling disconnection, running with and without the bios enabled, sending init command etc. In fact I think we have exhausted just about every option in the Adaptec SCSI setup utility - all to no provail. The response from the mailing lists was similar to the efforts mentioned above. Upon checking the problem database we see several occurances of timeout errors resembling VERY closely to the ones we are experienceing only they were with an earlier release and were only problems under heavy loads. We can not even get to the point which would initiate a load on the system. If you have any knowledge of this problem or have any solution suggestions they would be welcome.
