Hello, I hope that this is the right place to ask. I tried to open
an issue on github raspberrypi/linux but my account was flagged,
so I searched for another contact, since I don't know when it will
be unflagged.
I'm a new archlinuxarm user using a raspberry pi 4, and the
information required on gh would be:
Model: Raspberry Pi 4 Model B Rev 1.2
Firmware:
Jul 14 2021 14:20:55
(c) 2012 Broadcom
1ecd7d49359f3b48737f1a9e33c2f1513f90743d (clean) (release) (start)
Kernel version: Linux version 5.10.48-1-ARCH
What happen is that when I use wayland with this kernel
(5.10.48, commit 4a1f59200d36993f6b32742c03c154ae275bd89c)
the system freezes, while using (5.10.46-2, commit
64f5ffe846252ea43731ee8959ad4c13c70b9101) it doesn't.
On dmesg I get the following error:
[ +29.853154] Unable to handle kernel paging request at virtual
address dead000000000108
[ +0.008129] Mem abort info:
[ +0.002943] ESR = 0x96000044
[ +0.003351] EC = 0x25: DABT (current EL), IL = 32 bits
[ +0.005507] SET = 0, FnV = 0
[ +0.003291] EA = 0, S1PTW = 0
[ +0.003427] Data abort info:
[ +0.003084] ISV = 0, ISS = 0x00000044
[ +0.004094] CM = 0, WnR = 1
[ +0.003173] [dead000000000108] address between user and kernel
address ranges
I checked this by making an image containing the kernel,
sway (wayland compositor) and their dependencies (relative to
archlinux arm). The config.txt file contains the following:
hdmi_drive=1
disable_overscan=1
max_framebuffers=1
initramfs initramfs-linux.img followkernel
disable_splash=1
dtparam=audio=on
dtoverlay=disable-bt
dtoverlay=disable-wifi
dtoverlay=vc4-kms-v3d,cma-256
To reproduce, I start sway and move the mouse and press
some keys for few seconds until it freezes.
I've attached the full dmesg log to this email.
Thank you.
