Can you double check if this is happening only with the latest 6.8? Do you see anything similar in dmesg with other kernels? -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/2058191 Title: Getting SIGSEGV and SIGILL in many programs Status in Ubuntu: New Status in linux package in Ubuntu: New Bug description: Okay, recently I upgraded to 24.04. I'm getting some SIGSEGV and SIGILLs from time to time. Sometimes the entire computer freezes and i can't even turn down unless i hold the power button for 5 secs. I tought it could be the kernel version, so I upgraded from Ubuntu's 6.8.0-11.11+1 to mainline 6.8.1. However, it didn't fix. Here are some softwares i got SIGSEGV or SIGILLs: - code-insiders (vscode) - brave (Brave browser) - bun (node.js alternative) - node.js I know i should upload more logs, but I didn't find the errors in syslog or journalctl. $ lsb_release -rd ----------------- No LSB modules are available.
