Hi, I have never had to go to the extreme of posting on Usenet to solve a problem, but I have been struggling with this for weeks, and no other posts have helped me. In any case, here is the relevant system information: System: Dell PowerEdge 600SC RAID Card: LSI Logic CERC ATA/4ch RAID (Series 511 REV C2, BIOS Ver. 1.03) RAID Level: 5 Logical Drives: 1 Correct Driver: megaraid Detected Driver: megaraid_mbox Filesystem setup: (IDE RAID card shows logical drives as SCSI) /dev/sda1: /boot /dev/sda2: /data /dev/sda3: / /dev/sda4: SWAP I am trying to get any Fedora above FC2 working on it, and have tried FC3, FC4, and FC5. The problem is that both FC3 and FC4 detect the wrong card during installation, and that driver doesn't allow the setup program to access the logical drive. FC5 doesn't even offer the driver when the "noprobe" option is used, so I haven't made that work at all. I can get FC3/FC4 installed as long as I use the "noprobe" option and manually enter the correct driver. For some reason, both FC3 and FC4 identify the RAID card as (megaraid_mbox), which causes the installation to fail when it comes time to set up partitions. As long as I use "linux noprobe" and specify the (megaraid) driver instead of (megaraid_mbox) at the beginning of the installation, everything goes like clockwork. That is, until I try to update the thing. I have been using YUM to update linux lately, but I have also tried up2date on this system, with the same results. I suspect RPM would have the same problem. As soon as any new kernel package is installed, I cannot boot the system to the new kernel. If I select the old kernel from the grub menu, I can boot the system just fine as before, but of course, that means still using the old kernel. My guess about what is happening is that something in the installation program for the new kernel is causing the wrong driver, probably (megaraid_mbox) instead of (megaraid) to be set up as the hard disk driver for boot. If I set the system up on a normal IDE drive, connected to the system board instead of the RAID card, the updates run flawlessly, so I know it's a problem between this RAID card and Fedora. Here is the error message I get after installing a new kernel and trying to boot to that kernel: Uncompressing Linux... OK, booting the kernel. Red Hat nash version 4.2.15 starting mkrootdev: label / not found mount: error 2 mounting ext3 ERROR opening /dev/console!!!!:2 error dup2'ing fd of 0 to 0 error dup2'ing fd of 0 to 1 error dup2'ing fd of 0 to 2 switchroot: mount failed: 22 Kernel panic - not syncing: Attempted to kill init! Some of the things I have already tried before installing new kernel are: Resetting each partition name using mklabel Reformatting SWAP filesystem with version 2 type swap Remaking initrd images (though not positive I did it right) Changing reference to "megaraid_mbox" to "megaraid" in modprobe.conf & hwconf Renaming megaraid_mbox.ko and copying megaraid.ko to that filename Installing everything (except SWAP) on one partition Copying old kernel config and initrd files to new name of new kernel files None of those worked. So, needless to say, I need a lot of help. I'm all out of ideas, so I'm asking the gurus out there. Hopefully someone can help me. I think the most important point is that the new kernel installation is what is bad, somehow not incorporating the correct driver, since the original installation remains good, even after the new kernel is installed. I'm hoping it's something simple, but *any* help would be greatly appreciated. I will answer any further questions about my configuration if asked. This thing is driving me crazy! Thanks!!!
