Chromium from Asahi repos crashes everytime on launch with SIGILL

Hi all

Originally I tested Asahi Fedora on an M1 Mini, about a week ago

I am now running Asahi Fedora on an M2 Air and I have found that for some weird reason, Chromium does not launch.

I have installed it from the Asahi Fedora repos, and it does not appear to be a 16K page issue (have checked the binary).

Chromium is crashing with SIGILL on launch, every time.

Happy to supply any info required to help troubleshoot this.

What build of Chromium are you running? I’m running the latest 116.0.5845.96 build from the Fedora Asahi Remix repos on an M1 Ultra and it’s working fine.

Are there any entries in the Systemd journal that give you an idea of why it’s crashing? Also, have you tried removing the ~/.config/chromium/ directory to see if that fixes the issue?

Same build as you but this is on M2

That directory never gets created, Chromium never gets off the ground

Logs from journalctl during launch:

If it’s M2 specific it is likely a bti (Branch Target Identification). For confirmation please append arm64.nobti to the kernel command line and reboot.

confirmed, does not occur with arm64.nobti. possibly related to 1145581 - chromium - An open-source project to help move the web forward. - Monorail

Man you guys are clever :smiley: I assume I can add this to the kernel command line the usual ways?

I can confirm appending this to the kernel boot command results in Chromium working on my M2 device.
