[DragonFlyBSD - Bug #2705] panic: assertion "pv->pv_m == p" in pmap_remove_pv_pte

[bugtracker-admin at leaf.dragonflybsd.org]

Issue #2705 has been updated by kaz.

File Xorg.log.displaycorrupt added
File dmesg.displaycorrupt added
File messages.displaycorrupt added

Update: it doesn't seem to be my RAM after all -- I've tried running with either of my DIMMs removed, and the same display corruption occurred in either case. What I'm seeing is mainly letters being replaced with other letters, both in rxvt and firefox, starting soon (but not immediately) after I start up X. It usually locks up shortly after the corruption begins. It has started happening consistently with X running with xf86-video-intel. I'm trying vesa now; now problems so far.

I've attached some logs from after the display corruption begins, although I don't see anything unusual there.

----------------------------------------
A recently-installed machine running a recent git (my hardware had problems with the current release) has been crashing frequently when X is running; it hasn't consistently provided a core dump (maybe I rebooted it too quickly?), but I have two of them (attached). The first (3) was with X running, the second (4) was when I tried to open firefox. Firefox does sometimes open successfully. The crashes are frequent enough I've been keeping it in console.
