2GB swap partition limit?

[Émeric Maschino]

Thanks for your report.

I'm wondering if there's not something wrong with my LVM volume. anaconda
created a 4GB swap partition, but cat /proc/meminfo and cat /proc/swaps all
report it's in fact 2GB. Furthermore, I'm getting "Incorrect metadata area
header checksum" when my LV are mounted or when I enter lvdisplay at the lvm>
prompt.
