Batchbuffer dump & logs with DebugFlushCaches option

Forwarding a 855GM freeze bug with batchbuffer dumps from ubuntu user Pierre Monlong:
https://bugs.launchpad.net/ubuntu/+source/xserver-xorg-video-intel/+bug/477972

This bug may or may not be a duplicate of bug 24789, but I thought I'd report it here since it contains a fresh batchbuffer dump with updated driver and DebugFlushCaches option set.

[Problem]
Xorg freezes (GPU hangs) shortly after Xorg startup.

[Original report]
Binary package hint: xserver-xorg-video-intel

Since i've upgraded from 9.04 to 9.10 : The X server freezes shortly after it is started, no matter what I do. Usually this happens at the login procedure when i need to tape my password, or later when a use the System>Preferences menu in gnome desktop.
Mouse pointer remains functional (but clicking is not functionnal)

Very very close to this bug : https://bugs.launchpad.net/ubuntu/+source/xserver-xorg-video-intel/+bug/447892

See traces with the DebugFlushCaches option from the xserver-xorg-video-intel from xorg-edgers

The very same happens to me: same Laptop, same graphics chip.  I currently use OpenSuse 11.2 with KDE4. Let me know, if I can help!
Best,
D.

Just like for bug 24789, Pierre reports that these freezes stop when the kernel parameter acpi=off is used. He also did the following tests:

-2.4 intel driver from the x-retro repository (xserver-xorg-video-intel-2.4_2.4.1-1ubuntu11~ppa1_i386.deb) => OK works, good perf
-acpi=off boot option => OK works but poors performances (i don't know why)
-nomodeset boot option => KO freezes quickly after X startup
-"options i915 modeset=0" in /etc/modprobe.d/i915-kms.conf => KO freezes quickly after X startup (normal i think it's the same conf as previous)
-option "DRI" "Off" in xorg.conf => KO freezes quickly after X startup
-Option "PM" "Off" in xorg.conf => KO freezes quickly after X startup
-Option "NoMTRR" in xorg.conf => KO freezes quickly after X startup

Amilo M7400.. Same here.. I guess I'll run the 8.10. Installation went fine with the text mode option, but in the login only mouse is moving.

Slightly circumstantial evidence for incoherency: the IPEHR doesn't match the capture batch buffer.
