100% reproducable X hard lock with Intel 82865G

[Edd Barrett]

Hi,

This problem has been bugging me for a while. I had previously worked
around this by plugging in an old AGP card and using that (acceleration
broke for the AGP card in the last snap, but that is another story).

Matthieu is aware of the following issue. We discussed it on icb. I am
posting here in case any of the other hackers have any ideas.

When I boot this particular dell system, the system boots fine and the
console resolution is adjusted properly. When X is started, it locks up,
usually in less than a minute. The display does *not* switch back to the
console to show the crash. As far as I know (and from reading the cvs
history), it should.

I collected the following information from the serial console:

The panic that is firing is the else branch, line 564 of
/usr/src/sys/arch/amd64/amd64/bus_space.c.

Here is the ps output:

The kernel is stock GENERIC.MP. I built my own with debug symbols, which
it turned out, I did not need as the panic site was obvious. Tests a few
months back indicated that the same happens on the SP kernel too, but I
have not tried recently.

Dmesg follows:

It would be nice to have this fixed, as I use this machine for watching
movies etc. Whilst I can disable inteldrm to unfuck X, the
display is no longer accelerated and mplayer is too slow and cannot
scale the video to full-screen in hardware.

Cheers
