>Description:
My Thinkpad x260 hard-hangs when booting unless i915drmkms is disabled. Prior kernel from:
[ 1.000000] NetBSD 9.99.92 (GENERIC) #37: Tue Oct 26 21:23:49 PDT 2021
[ 1.000000] thorpej@the-ripe-vessel:/space/src/sys/arch/amd64/compile/GENERIC
boots fine and reports the GPU as such:
[ 1.015944] i915drmkms0 at pci0 dev 2 function 0: Intel HD Graphics 520 (GT2) (rev. 0x07)
.
.
.

[ 4.124557] intelfb0: framebuffer at 0xe0340000, size 1920x1080, depth 32, stride 7680
The hard-hang appears to happen after a fixed period of time. That is to say:
- First attempt to boot hung after displaying "Waiting for duplicate address detection to complete."
- Second attempt hung after displaying "Starting postfix." after moving all of my tap and bridge interfaces.
- Third attempt hung after displaying "Building databases: dev, utmp" (never displayed "utmpx") with a LOCKDEBUG kernel.
I cannot drop into DDB using C-A-ESC when this happens, and the fans spin up to full speed in short order.
>How-To-Repeat:
Boot 9.99.93 with the new DRM on Thinkpad x260.

N/A

State-Changed-From-To: open->feedback
State-Changed-By: riastradh@NetBSD.org
State-Changed-When: Sun, 22 May 2022 22:38:51 +0000
State-Changed-Why:
Can you update and try again?
If it still crashes the same way, can you build a kernel with
DDB_ONPANIC=1 and DDB_COMMANDONENTER="bt;show registers;sync",
and either see if you can get a crash dump or see if you can get
dmesg from the previous boot once it reboots, using userconf to
disable i915 on the next book?
