I'm pretty sure this has been tracked down to a buggy firmware in the
device itself, and the company (Huawei) is working on updating it to
solve the issue.

This is backed up by the fact that Huawei submitted the patch that is
said to have broken this device :)

I couldn't reproduce this problem in native and KVM environments.
This problem seems to be VMware specific and priority is low.
Alok Kataria queued this problem.
Thus, this problem has not yet solved but mainline kernels don't need to wait
for this problem.

Well, if you look at the report you'd notice that:

- I'm using a released, stable, distro (Arch Linux, basically vanilla) kernel. I hardly know how to compile one, let alone bisect it.
- I first had the problem on my 5+ year old Pentium 4 with equally old Intel graphics (845G chipset). I thought it would be hardware specific. But now I got a new Core 2 Duo with new Intel graphics (G45 chipset), moved to 64bit, and still have the exact same problem and exact same workaround. So I really don't believe anymore it's something hardware specific and should be quite general to anyone using Intel graphics. I hoped someone with much better knowledge could reproduce it and investigate it better.

On the report, Eric Anholt mentioned a likely cause and said that Jesse Barnes had looked into a similar issue before. I cc'd him (jbarnes) on last week reminder, but got no reply.

I really wish I could do more, but learning to compile a custom kernel for my hardware and do a git bisect is something I just can't afford now. If relevant people try to reproduce it but can't, and say only possible solution would be for me to bisect it I guess I could try to give it a go when I get some spare time.

Thanks,
Alberto.

I read at the report, but it wasn't obvious that you wouldn't be
able to bisect it.

Thank you Nick.

Since Arch Linux is not popular among kernel developers I just tested Fedora 10 Live-CD (KDE) and I can reproduce the exact same problem, even if Fedora 10 has kernel 2.6.27 and for me the problem appeared in .28 (but I guess Fedora adds many patches, so probably the "guilty" commit was backported to 2.6.27.5-117-FC10-i686).

Steps:
- Boot into Fedora 10 Live CD (obviously, into the default graphical mode)
- Install Powertop (yum install powertop) and run it
- I get about 60 wakeups per second from i915@pci.... leaving the system idle
- Switch to console and back to X. The wakeups are gone.

I hope that helps.

Ah ok, it sounds like you're getting vblank interrupts at startup time, but 
once you VT switch the kernel figures out that you don't need them, so it 
disables them.  I think this is a bug in the 2D driver; it has an ioctl it 
uses when doing modesetting which doubles as a "disabling the irq is ok" 
signal, but we call it at a time when the corresponding pipe is off, so the 
kernel ignores the call.

Can you file a bug for this at bugs.freedesktop.org?  Is it easy for you to 
rebuild & test xf86-video-intel driver patches?

Yes, that's what E. Anholt supposed too.

I filed the report:
http://bugs.freedesktop.org/show_bug.cgi?id=20296

Sure, I guess I can manage to patch the Intel driver and test it. I'm using 2.4.3 now, so maybe one thing I could do first is to try 2.5.x.

I provided some more traces using Ingo's "tip" branch, but I don't think
anyone has looked at them yet.

  http://bugzilla.kernel.org/show_bug.cgi?id=12465#c11

I can provide more traces if e.g. a different set of functions is
required, but I'm not going to be able to analyse them properly myself.

I should have a bit more time for testing next week and I plan to try
setting up the guest with the different virtual network adapters models
to see if that helps.

Cheers,
Kevin.

Subject: [PATCH] x86: oprofile: don't set counter width from cpuid on Core2

Impact: fix stuck NMIs and non-working oprofile on certain CPUs

Resetting the counter width of the performance counters on Intel's
Core2 CPUs, breaks the delivery of NMIs, when running in x86_64 mode.

This should fix bug #12395:
