Hi!
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?
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.
I did find this on the CURRENT mailing list, but it wont apply cleanly:
