I'm now in the difficult position of wondering whether to use the athlon up-to-date kernel(2.4.20-18.8smp) or the i686 older kernel(2.4.18-27.8.0smp) [or recompile my own]? (I prefer to use generic kernels and not bother recompiling). The reason I'm considering the older kernel is that the newer kernel seems to break the 2 bits of software that I want to run to manage my raid configuration, that is megamgr and /etc/init.d/raidmon[MegaCtrl/MegaServ] to manage an LSILogic Megaraid SCSI 320-2. Maybe I need to use the older athlon kernel but I'm not sure if RedHat makes these available? I only have the i686 version of the older kernel. Could you advise please? Do Ineed to wait for LSILogic to update their software or wait for a RedHat kernel that runs megaserv and megamgr?
