I have an "interesting" x86-32 system on thinkpad x60. Depending on kernel version, chromium either works or fails with floating point exception. Working: Linux amd 5.12.0+ #104 SMP PREEMPT Tue Apr 27 10:31:57 CEST 2021 i686 GNU/Linux Broken: Linux amd 5.15.0-rc5-next-20211015+ #204 SMP Sun Oct 17 10:29:18 CEST 2021 i686 GNU/Linux pavel@amd:~$ chromium --temp-profile Floating point exception (core dumped) Is there any chance to get anything useful from the coredump? Besides bisection, does someone have any ideas?
