Weird issue this.
About a minute after logging into KDE the system freezes, but only
partially. The keyboard is completely dead in all cases (no console
switching, no SysRq), but some tasks stay running. One time music continued
playing, other times it stopped. One time the desktop clock continued
ticking, other times it stopped. One time I could close a window using the
mouse, but other windows were frozen.
It's not just KDE that's frozen; one time I switched to VT1 before the
freeze happened, but that became unusable too.
Zilch in the logs.
I've bisected it down to:

[NDISC]: Fix race in generic address resolution
Confirmed that this is really the culprit by reverting this commit on top
of -rc2, which is now running fine.
I'm using IPv6 (local network only) together with IPv4, use a bridge (br0)
and have an NFS4 mount active.
I've encountered the same issue last Thursday. Here, I can hang my machine
with ping6. I've also bisected it down to the same commit.
I've sent some kernel traces which shows how the soft lock up occurs. See
thread: "[PATCH][RFC] race in generic address resolution"
