all of your mentioned options are enabled (since genkernel and me did it). i copied all data to another partition /dev/sdb9 and disabled initrd. by the way, i think that initrd was running, because all the scans after executing the initrd ran without problems. despite, i disabled it and got a kernel panic, like: """ [md] scanned 0 and added 0 ... VFS: cannot open root device "sdb9" or unknown block(0,0) please append correct "root=" ... Kernel panic - not syncing: VFS: unable to mount root fs on unknown-block(0,0) """ i don't know how to handel this error, since my grub entry is correct (or not?): """ title Gentoo Linux x86_64-2.6.28-5 (no initrd) (on /dev/sdb9) root (hd1,8) kernel /boot/kernel-genkernel-x86_64-2.6.28-gentoo-r5 root=/dev/sdb9 """ kind regards, der Max
