This crash happens reliably at 'Examining storage devices' in live install mode on my laptop, a Sony Vaio Z with two SSDs in an Intel BIOS RAID-0 (mdraid-handled) configuration (this is the factory setup). Fedora 14 is installed on the drive. If I select 'advanced' instead of 'basic', it becomes clear that anaconda's understanding of the disks/array is badly screwed up. It shows five disks with no model, vendor, interconnect or serial number, only capacity is listed for each. The capacities are 512 MB, 3072 MB, 553 MB, 0 MB and 0 MB. The number of drives matches the number of 'real' partitions in the array; there are six, but p4 is an extended partition containing p5 and p6, so the 'real' partitions are p1, p2, p3, p5 and p6 - five in total. If I do 'ls /dev/md*', I see /dev/md126 and /dev/md126p1 through /dev/md126p6 , which looks right. 'fdisk /dev/md126' and then 'p' shows a correct partition table for the array, so it seems like the kernel/mdraid are handling the array correctly, but anaconda isn't. Nautilus also shows the partitions on the array correctly and can mount and access them if I tell it to. er, that is, I pick 'specialized storage devices' rather than 'basic storage devices'. See also https://bugzilla.redhat.com/show_bug.cgi?id=678877 ; if I leave all the messed up 'drives' de-selected in the 'specialized storage devices' screen, and check off only a USB stick I also have plugged in, anaconda again crashes, but this time the bug is marked as being 678877. *** This bug has been marked as a duplicate of bug 678877 *** Created attachment 483941 [details]
