Description Susi Lehtola 2012-04-19 21:14:48 UTC 
The installation of Fedora 17 on my new desktop system hanged in the grub install. It turns out that the os-prober part of grub2-mkconfig hangs for some reason.

$ ps aux|grep grub
root      5207  0.0  0.0 112180  1620 pts/0    S+   00:10   0:00 /bin/sh /sbin/grub2-mkconfig

During the install the prober had worked for 10+ minutes, and nothing had happened. My partitioning is

and partitions 1 and 2 contain a Windows 7 installation (for playing Civilization V).


$ rpm -q grub2
grub2-1.99-19.fc17.x86_64
Comment 1 Susi Lehtola 2012-04-28 21:16:31 UTC 
Well, this is fixed in grub2-2.0-0.24.beta4.fc17.x86_64.
Comment 2 Mads Kiilerich 2012-04-30 10:57:18 UTC 
FWIW, I'm sure that it was something else than grub2 than fixed it:
