Version-Release number of selected component (if applicable): kernel-2.6.32-128.el6.x86_64 How reproducible: Always Steps to Reproduce: 1. Install snapshot-1 2. Boot the system and look at /proc/partitions 3. Install kernel-2.6.32-128.el6.x86_64 and reboot 4. Check /proc/partitions again. Or 1. Install snapshot-2 directly and check /proc/partitions. Actual results: With kernel-2.6.32-128.el6.x86_64 the megaraid boot device ends up being labeled sdb. On all previous kernels I've tested it is sda. Expected results: Additional info:
