Hi, Since a few days I am unable to start any application using electron/chromium on my laptop. I am using Debian Testing, kernel 6.10.11-amd64. So far, I've tried quite a variety of apps : zulip-desktop, signal-desktop, VS Code / Codium, Biwarden Directory Connector, discord, etc, all are failing with the same symptoms : on app startup, the window is displayed blank, then crash. I was able to find this trace in logs (this was a zulip startup but all other tested app generate very similar output) : qay kernel: BUG: kernel NULL pointer dereference, address: 0000000000000000 qay kernel: #PF: supervisor read access in kernel mode qay kernel: #PF: error_code(0x0000) - not-present page qay kernel: PGD 0 P4D 0 qay kernel: Oops: Oops: 0000 [#3] PREEMPT SMP PTI qay kernel: CPU: 11 PID: 35515 Comm: zulip Tainted: G D 6.10.11-amd64 #1 Debian 6.10.11-1 qay kernel: Hardware name: Dell Inc.

note: zulip[35515] exited with irqs disabled I can't find a lot of useful informations on the internet, but ended up stumbling upon this Github issue :https://github.com/Murmele/Gittyup/issues/783#issuecomment-2232940229. Author seems to have encountered a very similar issue (albeit on flatpak apps) and blaming it on Nouveau, which I'm also using. Is this mailing list the appropriate reporting channel ? I'm happy to add any required information or set a proper bug report on any relevant platform as needed.
