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 [*]: Copyright (c) 1992-2009 The FreeBSD Project.
