Hi I had a 3 disc raid5 array running fine with Fedora 7 (32bit) kernel 2.6.23.1-fc7 on an old Athlon XP using a two sata_sil cards. I replaced the hardware with an Athlon64 X2 and using the onboard sata_nv, after I modified the initrd I was able to boot up from my old system drive. However when it brought up the raid array it died with a kernel panic. I used a rescue CD, commented out the array in mdadm.conf and booted up. I could assemble the array manually (it kicked out one of the three drives for some reason?) but when I used mdadm --examine /dev/md0 I got the kernel panic again. I don't have remote debugging but I managed to take some pictures: http://img132.imageshack.us/img132/1697/kernel1sh3.jpg http://img132.imageshack.us/img132/3538/kernel2eu2.jpg >From what I understand it should be possible to do this hardware upgrade with using software raid? Any ideas?
