[PANIC] recent 7.2-STABLE when probing drm

Tue May 5 11:06:27 UTC 2009

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?

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 [*]:
