[Bug 228242] [NEW] [hardy] Freeze on Logout on AMD64

[4lorne]

Public bug reported:

When I log out on hardy, my computer becomes completely unresponsive
(cannot reset X with keyboard or switch to VTs) and the screen goes
black.  This also happens when I try to use the fast user switcher to
another user or if I kill X with Ctrl+Alt+Backspace (I suppose anything
that goes back to gdm).  This occurs with either compiz or metacity
running.

Also very strange:  When I hit the hard-reset button during a freeze, my
motherboard behaves very strangely.  It does not reset immediately.  It
stalls for a few seconds, then shuts down for a moment, then turns on.
My network administrator tells me that when I do this, my computer's NIC
brings down the entire switch.  Yikes!

While the computer is on, I am able to switch to virtual terminals with
no problem.  Shutting down and restarting also works fine.

This problem occurs when booting of my hard drive as well as booting off
the Hardy AMD64 LiveCD.  This does not happen if I boot off my hard
drive and using the Gutsy AMD64 Kernel.  It also does not happen when I
boot off the Hardy x86 LiveCD.  When booting off the LiveCDs, I've
stripped my computer to the minimum hardware with only CPU, RAM and CD-
ROM connected.

My Hardware
-ASUS P5E-VM HDMI (BIOS v. 505)
 - Using onboard Intel X3500
-Intel E6750
-2x1GB Dual channel DDR2800 OCZ RAM.  Voltage raised to 2.00V in BIOS (solution to stability issues for this Mobo/RAM combo)
