Description Bernie Hoefer 2025-07-16 21:58:23 UTC

I'm running Fedora Linux 41 on an Intel(R) Pentium(R) CPU G2030 @ 3.00GHz machine.  Its window manager is (non-Wayland) Xfce.

After updating from:
  chromium-137.0.7151.103-1.fc41.x86_86
to:
  chromium-138.0.7204.49-1.fc41.x86_86
...it will no longer start. Trying to start it from the command line:


  $ chromium-browser about:blank
  Illegal instruction (core dumped)


...but no vmcore is left in my $HOME or /tmp. Updating to chromium-138.0.7204.100-1.fc41.x86_86 did not resolve the issue.

I've read that "Illegal instruction" means that a CPU instruction was executed that is not valid for my CPU.  I've looked through Chrome's release notes but nothing stands out as a possible cause.

As a final data point, I'm also running Fedora Linux 41 on a AMD Ryzen 7 PRO 8840HS w/ Radeon 780M Graphics (again with non-Wayland Xfce) and Chromium works fine there. So again I'm wondering if there is something about my old Intel CPU causing Chromium to crash.

Reproducible: Always

Is https://discussion.fedoraproject.org/t/where-is-chromiums-debuginfo-package/159053 an example of this?

I do not think so.  My strace output (which has been attached to this Bugzilla ticket as a private attachment) shows:

  --- SIGILL {si_signo=SIGILL, si_code=ILL_ILLOPN, si_addr=0x7fa01939439d} ---
  +++ killed by SIGILL (core dumped) +++

...and it and my abrt output does not mention anything about the need for debug packages or symbols.
