Hi I just updated the kernel from 2.6.13-1.1532_FC4 to 2.6.14-1.1637_FC4 (i686 both). Rebooted and i had lost 2 hard disk connected to the PATA Promise controller. Rebooted back with the 2.6.13 and the disk were again detected. I dmesg the 2.6.14 and it detected the the 2 IDE channels, the 2 VIA SATA and the 2 PROMISE SATA, but nothing about the 2 Promise PATA. Any ideas??? My motherboard is a Asus K8V SE Deluxe and I really need the promise PATA since these disk are part of a logical volume :(( Thanks in advance... ZenDark
