I installed a Redhat enterprise AS 4 Update 3, kernel 2.6.9-34.ELsmp. on a Tyan Thunder K8SE with a dual core AMD opteron and a 3ware 9550SX SATA RAID controller. I build a 4 disk RAID 5 with the root partition (/) build on /dev/mapper/VolGroup00-LogVol00. At the end of installation process All appear running OK, also after the first reboot all run fine. After the automatic update from RedHat network, with new kernel: 2.6.9-34.0.2.ELsmp at boot time the system hangup with these messages: ... .. No volume groups found Unable to find volume group ?VolGroup00? ... ... ... Kernel panic ... Can anyone help me ?
