Daniel, the InfraRed reciever (which would appear to be built in to the
XPS) may be the culprit. If you could switch it off in the BIOS and
retest that might tell us whether that is infact the problem.
Alternatively, blacklist the 'ite-cir' module.

Hi Brendan and Daniel,
Can you confirm if you see this same issue with Precise on this system
(ie. 3.2.0-23.36 kernel)? It looks similar to the issue being seen on
bug 972723. The bug reporters there have documented a workaround and
analysis in comments #10 and #11 in bug 972723. They have
OK, as per Brendan's suggestion I blacklisted the ite-cir module, by
creating /etc/modprobe.d/blacklist-ite-cir.conf with this content:
blacklist ite_cir
then I rebooted with the 3.0.0-19 kernel and it boots fine!
And to confirm that the ite-cir module is the one causing the problem, I
did
Note that this is also happening on Precise, see bug 972723.

Confirmed with Daniel that this is present in Precise. Disabling the IR
reciever is not going to block certification so we wouldn't have any
objections.

Brendan and Daniel,
Could we also get testing with the following as well. It it more along
the lines of a proper fix:

@Leann:
I tested with Precise's daily image, kernel 3.2.0-23.36, and I still see
this problem on boot, so yes, it's present on recent Precise builds.
Also, I tried blacklisting the module in the kernel command line, if I
make it so the module doesn't load on boot, then the system boots fine.
Hi,
I tested again with the kernel from #10, the system boots OK, and once
it's booted I can see the ite_cir module :
ubuntu@200912-4906:~$ lsmod |grep ite_cir
ite_cir24743 0
rc_core21263 10
I've uploaded another test kernel for Oneiric with the same fix here:
http://people.canonical.com/~henrix/lp984387-postponeirq-oneiric/
Could someone running Oneiric give it a try and report back?
