>Category: DRM (???) related system crash/freeze
>Environment:
System : OpenBSD 7.2
Details : OpenBSD 7.2 (GENERIC.MP) #4: Mon Dec 12 06:06:42 MST 2022
[email protected]:/usr/src/sys/arch/amd64/compile/GENERIC.MP
Architecture: OpenBSD.amd64
Machine : amd64
>Description:
I've been seeing occasional system freezes/crashes on my Lenovo
T490 laptop. Sometimes (rarely!) I do get a ddb prompt, but most
of the times the system simply switches from X to console and I
can't do anything. Here's what I see in the console with the last
crash I got (warning: manually typed):
panic: pmap_enter: PG_PVLIST mapping with unmanaged page: va
0xb47ba6f5000, opte 0x800002054f317465, pa 0x54f317000
I'll attach a photo with the backtrace of a different crash.
>How-To-Repeat:
I don't have a reliable way of reproducing the issue. But it
seems to be happening more frequently after recent upgrades (there
was a recent i915 patch, but I can't claim it's related.) Most of
the times, running a firefox for a while will eventually trigger
this.
