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

[bugtracker-admin at leaf.dragonflybsd.org]

Issue #2705 has been updated by kaz.

Status changed from New to Closed

This computer just had an episode of all kinds of display corruption (some weird colors on the screen, letters garbled in firefox). I think this is likely a RAM problem. I haven't been able to get all the way through a memtest pass because this old laptop overheats; I'll probably try sticking the RAM in another computer to test it properly. Anyway, I'll reopen this if further investigation suggests it isn't a hardware fault but otherwise this can just be ignored.

----------------------------------------
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.
