Description of problem: Started with FC1, not 1.90. And the 2.4 kernels still boot fine. But 2.6 kernels I have added fail to boot. pci=noacpi and acpi=off help it get further so it successfully recognizes and binds partitions to the raid1 devices, but it fails to mount the ext3 root filesystem contained within. That causes pivot_root to fail, and init to not be found, resulting in a panic. Boot messages captured on a serial console are attached. Version-Release number of selected component (if applicable): kernel-2.6.3-2.1.253 i686 How reproducible: Always Steps to Reproduce: 1. Boot 2.6.3 i686 kernel from rawhide rpms on DL360 P21 2. 3. Actual Results: Kernel panic Expected Results: Normal boot like 2.4 kernels do. Additional info: This is 1GHz P4 processor with two SCSI drives, all partitions (except swap) mirrored across the drives using software raid 1. The hardware raid controller board has been removed from the SCSI controller, thus is not a factor. The P21 BIOS has been flashed to 11/15/2002 (the latest).

Problem solved! I upgraded mkinitrd and modutils packages from rawhide and installed packages device-mapper and lvm2 to resolve dependencies. Then I made a new initrd and rebooted. Using FC1's mkinitrd and/or modutils was the cause of the 2.6 boot problem.
