I also had a SERIOUS problem installing Fedora 12 on a Dell Optiplex GX620 which *appears* to be the same thing.
I tried to install Fedora 12 on a Dell Optiplex GX620 as a 64-bit OS (x86_64), using BIOS revision A10. When the disk was busy installing things it suddenly hung with this message:
kernel: mpage_da_map_blocks block allocation failed for inode 211 at logical offset 0 with max blocks 1 with error -30
kernel: This should not happen.!! Data will be lost
On each boot, I needed to add kernel entry
iommu=soft
Later I modified /boot/grub/grub.conf so all entries for kernel added:
iommu=soft
Previously I had tried to upgrade the BIOS to rev. A11; this caused complete loss of the USB keyboard/mouse, so I re-installed revision A10.
I'm in the middle of an install now that the iommu=soft setting has been added; so far, this *appears* to have solved the problem.
