Finally decided I need some help with this one. I get a kernel panic on several installs of f7t3: iso dvd, and 2 http installs from rawhide, different snapshots. Same issue with iso dvd install of f7t4. All appear to install normally to sdc which is a wd 160 gig pata. Machine also has 2 sata2 drives in raid 1 configuration running centos 5. Here is hardware setup: asus A8N-SLI cpu amd 64 X2 4400+ 2 gigs ram 2 maxtor sata2 1 wd pata [root@office bmcclure]# fdisk -l Disk /dev/hda: 160.0 GB, 160041885696 bytes 255 heads, 63 sectors/track, 19457 cylinders Units = cylinders of 16065 * 512 = 8225280 bytes Device Boot Start End Blocks Id System /dev/hda1 * 1 13 104391 83 Linux /dev/hda2 14 1925 15358140 83 Linux /dev/hda3 1926 19457 140825790 83 Linux Disk /dev/sda: 160.0 GB, 160041885696 bytes 255 heads, 63 sectors/track, 19457 cylinders Units = cylinders of 16065 * 512 = 8225280 bytes Device Boot Start End Blocks Id System /dev/sda1 * 1 13 104391 fd Linux raid autodetect /dev/sda2 14 3837 30716280 fd Linux raid autodetect /dev/sda3 3838 3901 514080 fd Linux raid autodetect /dev/sda4 3902 19457 124953570 5 Extended /dev/sda5 3902 19457 124953538+ fd Linux raid autodetect Disk /dev/sdb: 160.0 GB, 160041885696 bytes 255 heads, 63 sectors/track, 19457 cylinders Units = cylinders of 16065 * 512 = 8225280 bytes Device Boot Start End Blocks Id System /dev/sdb1 * 1 13 104391 fd Linux raid autodetect /dev/sdb2 14 3837 30716280 fd Linux raid autodetect /dev/sdb3 3838 3901 514080 fd Linux raid autodetect /dev/sdb4 3902 19457 124953570 5 Extended /dev/sdb5 3902 19457 124953538+ fd Linux raid autodetect Disk /dev/md1: 31.4 GB, 31453347840 bytes 2 heads, 4 sectors/track, 7679040 cylinders Units = cylinders of 8 * 512 = 4096 bytes Disk /dev/md1 doesn't contain a valid partition table Disk /dev/md3: 127.9 GB, 127952355328 bytes 2 heads, 4 sectors/track, 31238368 cylinders Units = cylinders of 8 * 512 = 4096 bytes Disk /dev/md3 doesn't contain a valid partition table Disk /dev/md2: 526 MB, 526319616 bytes 2 heads, 4 sectors/track, 128496 cylinders Units = cylinders of 8 * 512 = 4096 bytes Disk /dev/md2 doesn't contain a valid partition table Disk /dev/md0: 106 MB, 106823680 bytes 2 heads, 4 sectors/track, 26080 cylinders Units = cylinders of 8 * 512 = 4096 bytes Disk /dev/md0 doesn't contain a valid partition table I understand the above hda drive is seen by f7 as sdc. Here is the error message: mount:could not find filesystem '/dev/root' setuproot: moving /dev failed: No such file or directory setuproot: error mounting /proc: No such file or directory setuproot: error mounting /sys: No such file or directory switchroot:mount failed: No such file or directory Kernel panic - not syncing:Attempted to kill init! Booting in linux rescue mode I get a screen full of garbage characters and a "You have no linux partitions" error message and drops me to a shell. Running fdisk -l shows normal partitions for sdc. I can mount the f7t4 partitions from centos 5 and all looks normal AFAICT.

Any help much appreciated. As an aside, I did an install on an old asus A7N8X wd pata drive and all went well with no known issues. Thanks agaain. B.J.
