[PANIC] recent 7.2-STABLE when probing drm
Guido Falsi
I'm using FreeBSD/i386 stable on a HP DC7800 PC.
It has an Intel Q35 graphic chip.
After upgrading to a recent stable I experienced a pani on boot, just
after probing drm.
I investigated a little and found out that reverting the file
src/sys/dev/pci/pci.c
to rev. 1.355.2.9 (SVN Rev 190092) solves the crash.
I could not investigatte urther right away, but some regression was
introduced with this rev.
Is any more information needed?
Thank you in advance for any help or information on this.
Here is the dmesg from the working kernel the other one panics just
after the line marked with [*]:

When it panics, can you please type "bt" (assuming you have the debugger
compiled in) and show the output?

I wonder if r189373 also needs merging?

I did not have a kernel with debugger handy.

Looking at a thread on -current, it looks like this is probably the
case. It's not a straight merge from head as other bits have changed,
but you could test http://people.freebsd.org/~gavin/189373_7.diff
(warning: compile tested only)

Thanks for the hint. We need both r183095 and r189373, but the
actual bugfix is r189373, as you rightly pointed out. Below is the patch
that works for me.

I want to add a "me too". I can't compile in a debugger as my sources
are updated to 7.2, and any kernel built panics with the same message.

Tested the patch, it solves the problem. The system now boots cleanly.
Im using the PC as normal with no ill effects with this new kernel.

Yes, that looks right, resources are owned by both agp and drm on Intel.

Sorry about that. I merged the fixes to vgapci this morning so this
