I have a Tyan Thunder K8SR (S2881) with 1 x 248 AMD Opteron, 2 GB RAM, 4 SATA disks (2 Raid 1 sets). I install in text mode and select nothing (=minimal). The installation runs smoothly until 33% of "Performing post install configuration...". Then there is a kernel panic. This problem occurs with Fedora Core 2 x68_64 as well as with Fedora Core 3 Test 3 x64_64.
Seems to be a hardware failure. I have a second identical computer which I just pulled out of the box and there, installation worked without problems. Sorry to have bothered you.
