Hello, Stephen and Tony.
I think Tony is right, but LVM problems might just be a symptom of the
underlying trouble, not the cause. Modprobe is in i/o wait state while
"vol_id" is probing your disks, looking for volume labels. If there are
read errors on a faulty hard disk, for example, it can take a long time
for the kernel drivers to give up. Have you run any disk diagnostics?
Another possibility is that you might have corrupted partition tables
and/or you are waiting for non-existent UUID's to be discovered. The
fstab entries in Gutsy now use UUID's instead of device names and these
UUID's are intended to be persistent across changes to the BIOS-derived
device names caused by adding/removing disks.
BTW, Thanks for introducing me to bootchart :-)
