The same problem happened with a server after I upgrade the kernel to 2.6.9-42.0.2. Another server, with similar configuration, boots normally on new kernel. Both uses software RAID and LVM2, (/boot on md0 and Logical Volume on md1). Only differences between the servers is HD, on first have two Seagate (ST380013AS Rev: 3.18) 80 GB, another have two Western Digital (WDC WD2000JD-55H Rev: 08.0) 120 GB. As it is a production server, I didn't make any test to investigate the problem, just boot on previous kernel. Heitor A. M.
