Can you log into a vt and tail ~/.xsession-errors and see anything
useful in there? I use a vt for this so konsole is not in the mix while
trying to tail stuff.

I've historically found that lockups of around 30 seconds are so are
often DNS lookup failures, and lockups of 1-2 minutes are often
IO timeouts (in my case usually nfs or smb mounts that went away when I
did something stupid hehehehe )

You can also try stracing the kdeinit process to see what they are
doing and where they are blocking. With KDE it's a lot harder to find
the process to trace (there are so *many* process), sorting top on the
"S" column can help - look for stuff listed as "D" in that column.

While we discuss KDE, any idea why my panel will occasionally stop
receiving mouse events and updates occasionally after coming out of
suspend? When this happnes, the clock stops ticking. Very annoying....
