While upgrading from version 5.2 to 6.1 I experienced the following bug: I have an Adaptec 2920 scsi card which, of course, requires aic7xxx.o to run. The install/upgrade program detects the right board and loads the driver appropriately. However, for some reason, the install program places the aic151 module in conf.modules and consequently gets the wrong driver built into the ramsdisk. When my server restarted I could see the scsi driver failing to load and, of course, kernel panic. I have been able to work around this problem by putting the right entry in conf.modules during the install program (escaping to console, copying file to another machine and editing - a long process, especially if the local filesystems are not mounted) Thanks - I hope I provided you with good information
Unfortunately, we don't have a 2920. Itried with a 2940 which uses the same aic7xxx driver. I installed 5.2, then upgraded to 6.1 and had no problems. I also installed 5.2 and upgraded to 6.2 and had no problems. conf.modules was correct each time.
